This extensive review provides in-depth information on the molecular complexity of laminins and the current knowledge of their diversity and different functional roles. The review gives the reader an understanding of the importance of laminins for different cell- and tissue types in both normal and pathological functioning in mammals at different stages of development and function.

This paper compares purified laminins to human recombinant laminins. The major findings are that laminin preparations that have been purified from different tissues (in contrast to recombinantly produced laminins) consist of fragmented proteins, different laminin isoforms and unwanted, contaminating fibronectin. In addition to undefined and heterogenous preparations, they show large batch-to-batch variations. In conclusion, only human recombinant laminins maintains the full integrity and biological activity of laminins and make them the optimal preparations for cell cultivation.

In this concise review the authors describe that it is now feasible to establish clinical-grade hESC lines in animal substance-free chemically defined conditions with the Laminin-521 matrix. They discuss recent developments and the progress to now being able to generate genetically stable hESC lines even from single biopsied blastomeres without destroying the embryo.

Short review on establishment of hESC lines on LN-521. Authors state that they easily can establish and expand hESC lines in fully chemically defined animal substance free conditions. hESC lines can be derived from single biopsied cells of embryos that need not be destroyed during the process. The genetic stability and differentiation capacity can be studied. These cell lines can today be safely expanded almost without limitations.

In this review, the authors look at different large-scale hPSC culture growth components by comparing cell culture methods (matrices, media etc.) and identifying the advantage and disadvantages and pitfalls associated with each one. Since laminin-521 was not available when the review was written, they only mention laminin-511 where the cells are seeded as clumps (Rodin et al 2010). The only disadvantage mentioned regarding laminin-511 is that the use of laminin for maintenance and expansion will be to thigh due to the price of the laminins.

Here, the author summarize the role of the ECM and integrins in the formation of three germ layer progenies. Various ECM–integrin interactions were found, facilitating differentiation toward definitive endoderm, hepatocyte-like cells, pancreatic beta cells, early mesodermal progenitors, cardiomyocytes, neuro-ectoderm lineages, and epidermal cells, such as keratinocytes and melanocytes.
