--- _id: '1285' abstract: - lang: eng text: Cell migration is central to a multitude of physiological processes, including embryonic development, immune surveillance, and wound healing, and deregulated migration is key to cancer dissemination. Decades of investigations have uncovered many of the molecular and physical mechanisms underlying cell migration. Together with protrusion extension and cell body retraction, adhesion to the substrate via specific focal adhesion points has long been considered an essential step in cell migration. Although this is true for cells moving on two-dimensional substrates, recent studies have demonstrated that focal adhesions are not required for cells moving in three dimensions, in which confinement is sufficient to maintain a cell in contact with its substrate. Here, we review the investigations that have led to challenging the requirement of specific adhesions for migration, discuss the physical mechanisms proposed for cell body translocation during focal adhesion-independent migration, and highlight the remaining open questions for the future. acknowledgement: We would like to thank Dani Bodor for critical comments on the manuscript and Guillaume Salbreux for discussions.

This process occurs in several consecutive steps. Upon entry into lymphatic capillaries, DCs first actively crawl into downstream collecting vessels. From there, they are next passively and rapidly transported to the dLN by lymph flow. Here, we describe a role for the chemokine CCL21 in intralymphatic DC crawling. Performing time-lapse imaging in murine skin, we found that blockade of CCL21-but not the absence of lymph flow-completely abolished DC migration from capillaries toward collecting vessels and reduced the ability of intralymphatic DCs to emigrate from skin. Moreover, we found that in vitro low laminar flow established a CCL21 gradient along lymphatic endothelial monolayers, thereby inducing downstream-directed DC migration. These findings reveal a role for intralymphatic CCL21 in promoting DC trafficking to dLNs, through the formation of a flow-induced gradient. author: - first_name: Erica full_name: Russo, Erica last_name: Russo - first_name: Alvaro full_name: Teijeira, Alvaro last_name: Teijeira - first_name: Kari full_name: Vaahtomeri, Kari id: 368EE576-F248-11E8-B48F-1D18A9856A87 last_name: Vaahtomeri orcid: 0000-0001-7829-3518 - first_name: Ann full_name: Willrodt, Ann last_name: Willrodt - first_name: Joël full_name: Bloch, Joël last_name: Bloch - first_name: Maximilian full_name: Nitschké, Maximilian last_name: Nitschké - first_name: Laura full_name: Santambrogio, Laura last_name: Santambrogio - first_name: Dontscho full_name: Kerjaschki, Dontscho last_name: Kerjaschki - first_name: Michael K full_name: Sixt, Michael K id: 41E9FBEA-F248-11E8-B48F-1D18A9856A87 last_name: Sixt orcid: 0000-0002-6620-9179 - first_name: Cornelia full_name: Halin, Cornelia last_name: Halin citation: ama: Russo E, Teijeira A, Vaahtomeri K, et al.

Opposed to early assumptions, chemokines do not necessarily act as soluble cues but are often immobilized within tissues, e.g., dendritic cell migration toward lymphatic vessels is guided by a haptotactic gradient of the chemokine CCL21. Controlled assay systems to quantitatively study haptotaxis in vitro are still missing. In this chapter, we describe an in vitro haptotaxis assay optimized for the unique properties of dendritic cells. The chemokine CCL21 is immobilized in a bioactive state, using laser-assisted protein adsorption by photobleaching. The cells follow this immobilized CCL21 gradient in a haptotaxis chamber, which provides three dimensionally confined migration conditions. acknowledged_ssus: - _id: Bio acknowledgement: This work was supported by the Boehringer Ingelheim Fonds, the European Research Council (ERC StG 281556), and a START Award of the Austrian Science Foundation (FWF).

Despite its importance, basic questions regarding force transduction\r\nor directional sensing are still heavily investigated. Directed migration of cells\r\nguided by immobilized guidance cues - haptotaxis - occurs in key-processes,\r\nsuch as embryonic development and immunity (Middleton et al., 1997; Nguyen\r\net al., 2000; Thiery, 1984; Weber et al., 2013). Immobilized guidance cues\r\ncomprise adhesive ligands, such as collagen and fibronectin (Barczyk et al.,\r\n2009), or chemokines - the main guidance cues for migratory leukocytes\r\n(Middleton et al., 1997; Weber et al., 2013). While adhesive ligands serve as\r\nattachment sites guiding cell migration (Carter, 1965), chemokines instruct\r\nhaptotactic migration by inducing adhesion to adhesive ligands and directional\r\nguidance (Rot and Andrian, 2004; Schumann et al., 2010). Quantitative analysis\r\nof the cellular response to immobilized guidance cues requires in vitro assays\r\nthat foster cell migration, offer accurate control of the immobilized cues on a\r\nsubcellular scale and in the ideal case closely reproduce in vivo conditions. The\r\nexploration of haptotactic cell migration through design and employment of such\r\nassays represents the main focus of this work.\r\nDendritic cells (DCs) are leukocytes, which after encountering danger\r\nsignals such as pathogens in peripheral organs instruct naïve T-cells and\r\nconsequently the adaptive immune response in the lymph node (Mellman and\r\nSteinman, 2001). To reach the lymph node from the periphery, DCs follow\r\nhaptotactic gradients of the chemokine CCL21 towards lymphatic vessels\r\n(Weber et al., 2013). Questions about how DCs interpret haptotactic CCL21\r\ngradients have not yet been addressed. The main reason for this is the lack of\r\nan assay that offers diverse haptotactic environments, hence allowing the study\r\nof DC migration as a response to different signals of immobilized guidance cue.\r\nIn this work, we developed an in vitro assay that enables us to\r\nquantitatively assess DC haptotaxis, by combining precisely controllable\r\nchemokine photo-patterning with physically confining migration conditions. With this tool at hand, we studied the influence of CCL21 gradient properties and\r\nconcentration on DC haptotaxis. We found that haptotactic gradient sensing\r\ndepends on the absolute CCL21 concentration in combination with the local\r\nsteepness of the gradient. Our analysis suggests that the directionality of\r\nmigrating DCs is governed by the signal-to-noise ratio of CCL21 binding to its\r\nreceptor CCR7. Moreover, the haptotactic CCL21 gradient formed in vivo\r\nprovides an optimal shape for DCs to recognize haptotactic guidance cue.\r\nBy reconstitution of the CCL21 gradient in vitro we were also able to\r\nstudy the influence of CCR7 signal termination on DC haptotaxis. To this end,\r\nwe used DCs lacking the G-protein coupled receptor kinase GRK6, which is\r\nresponsible for CCL21 induced CCR7 receptor phosphorylation and\r\ndesensitization (Zidar et al., 2009). We found that CCR7 desensitization by\r\nGRK6 is crucial for maintenance of haptotactic CCL21 gradient sensing in vitro\r\nand confirm those observations in vivo.\r\nIn the context of the organism, immobilized haptotactic guidance cues\r\noften coincide and compete with soluble chemotactic guidance cues. During\r\nwound healing, fibroblasts are exposed and influenced by adhesive cues and\r\nsoluble factors at the same time (Wu et al., 2012; Wynn, 2008). Similarly,\r\nmigrating DCs are exposed to both, soluble chemokines (CCL19 and truncated\r\nCCL21) inducing chemotactic behavior as well as the immobilized CCL21. To\r\nquantitatively assess these complex coinciding immobilized and soluble\r\nguidance cues, we implemented our chemokine photo-patterning technique in a\r\nmicrofluidic system allowing for chemotactic gradient generation. To validate\r\nthe assay, we observed DC migration in competing CCL19/CCL21\r\nenvironments.\r\nAdhesiveness guided haptotaxis has been studied intensively over the\r\nlast century. However, quantitative studies leading to conceptual models are\r\nlargely missing, again due to the lack of a precisely controllable in vitro assay. A\r\nrequirement for such an in vitro assay is that it must prevent any uncontrolled\r\ncell adhesion. This can be accomplished by stable passivation of the surface. In\r\naddition, controlled adhesion must be sustainable, quantifiable and dose\r\ndependent in order to create homogenous gradients. Therefore, we developed a novel covalent photo-patterning technique satisfying all these needs. In\r\ncombination with a sustainable poly-vinyl alcohol (PVA) surface coating we\r\nwere able to generate gradients of adhesive cue to direct cell migration. This\r\napproach allowed us to characterize the haptotactic migratory behavior of\r\nzebrafish keratocytes in vitro. Furthermore, defined patterns of adhesive cue\r\nallowed us to control for cell shape and growth on a subcellular scale." acknowledged_ssus: - _id: Bio - _id: PreCl - _id: LifeSc acknowledgement: "First, I would like to thank Michael Sixt for being a great supervisor, mentor and\r\nscientist.

Especially I would like to thank\r\nDaria for her advice and encouragement during our regular progress meetings.\r\nI also want to thank the team and fellows of the Boehringer Ingelheim Fond\r\n(BIF) PhD Fellowship for amazing and inspiring meetings and the BIF for\r\nfinancial support.\r\nImportant factors for the success of this thesis were the warm, creative\r\nand helpful atmosphere as well as the team spirit of the whole Sixt Lab.\r\nTherefore I would like to thank my current and former colleagues Frank Assen,\r\nMarkus Brown, Ingrid de Vries, Michelle Duggan, Alexander Eichner, Miroslav\r\nHons, Eva Kiermaier, Aglaja Kopf, Alexander Leithner, Christine Moussion, Jan\r\nMüller, Maria Nemethova, Jörg Renkawitz, Anne Reversat, Kari Vaahtomeri,\r\nMichele Weber and Stefan Wieser. We had an amazing time with many\r\nlegendary evenings and events. Along these lines I want to thank the in vitro\r\ncrew of the lab, Jörg, Anne and Alex, for lots of ideas and productive\r\ndiscussions. I am sure, some day we will reveal the secret of the ‘splodge’.\r\nI want to thank the members of the Heisenberg Lab for a great time and\r\nthrilling kicker matches. In this regard I especially want to thank Maurizio\r\n‘Gnocci’ Monti, Gabriel Krens, Alex Eichner, Martin Behrndt, Vanessa Barone,Philipp Schmalhorst, Michael Smutny, Daniel Capek, Anne Reversat, Eva\r\nKiermaier, Frank Assen and Jan Müller for wonderful after-lunch matches.\r\nI would not have been able to analyze the thousands of cell trajectories\r\nand probably hundreds of thousands of mouse clicks without the productive\r\ncollaboration with Veronika Bierbaum and Tobias Bollenbach. Thanks Vroni for\r\ncountless meetings, discussions and graphs and of course for proofreading and\r\nadvice for this thesis. For proofreading I also want to thank Evi, Jörg, Jack and\r\nAnne.\r\nI would like to acknowledge Matthias Mehling for a very productive\r\ncollaboration and for introducing me into the wild world of microfluidics. Jack\r\nMerrin, for countless wafers, PDMS coated coverslips and help with anything\r\nmicro-fabrication related. And Maria Nemethova for establishing the ‘click’\r\npatterning approach with me. Without her it still would be just one of the ideas…\r\nMany thanks to Ekaterina Papusheva, Robert Hauschild, Doreen Milius\r\nand Nasser Darwish from the Bioimaging Facility as well as the Preclinical and\r\nthe Life Science facilities of IST Austria for excellent technical support. At this\r\npoint I especially want to thank Robert for countless image analyses and\r\ntechnical ideas. Always interested and creative he played an essential role in all\r\nof my projects.\r\nAdditionally I want to thank Ingrid and Gabby for welcoming me warmly\r\nwhen I first started at IST, for scientific and especially mental support in all\r\nthose years, countless coffee sessions and Heurigen evenings. #BioimagingFacility #LifeScienceFacility #PreClinicalFacility" alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Jan full_name: Schwarz, Jan id: 346C1EC6-F248-11E8-B48F-1D18A9856A87 last_name: Schwarz citation: ama: Schwarz J.
