Roles of integrins in human induced pluripotent stem cell growth on Matrigel and vitronectin.
Stem cells and development 2010 AUG
Abstract
Human induced pluripotent stem cells (iPSCs) hold promise as a source of adult-derived,patient-specific pluripotent cells for use in cell-based regenerative therapies. However,current methods of cell culture are tedious and expensive,and the mechanisms underlying cell proliferation are not understood. In this study,we investigated expression and function of iPSC integrin extracellular matrix receptors to better understand the molecular mechanisms of cell adhesion,survival,and proliferation. We show that iPSC lines generated using Oct-3/4,Sox-2,Nanog,and Lin-28 express a repertoire of integrins similar to that of hESCs,with prominent expression of subunits alpha5,alpha6,alphav,beta1,and beta5. Integrin function was investigated in iPSCs cultured without feeder layers on Matrigel or vitronectin,in comparison to human embryonic stem cells. beta1 integrins were required for adhesion and proliferation on Matrigel,as shown by immunological blockade experiments. On vitronectin,the integrin alphavbeta5 was required for initial attachment,but inhibition of both alphavbeta5 and beta1 was required to significantly decrease iPSC proliferation. Furthermore,iPSCs cultured on vitronectin for 9 passages retained normal karyotype,pluripotency marker expression,and capacity to differentiate in vitro. These studies suggest that vitronectin,or derivatives thereof,might substitute for Matrigel in a more defined system for iPSC culture.
Chemically defined conditions for human iPSC derivation and culture.
Nature methods 2011 MAY
Abstract
We re-examine the individual components for human embryonic stem cell (ESC) and induced pluripotent stem cell (iPSC) culture and formulate a cell culture system in which all protein reagents for liquid media,attachment surfaces and splitting are chemically defined. A major improvement is the lack of a serum albumin component,as variations in either animal- or human-sourced albumin batches have previously plagued human ESC and iPSC culture with inconsistencies. Using this new medium (E8) and vitronectin-coated surfaces,we demonstrate improved derivation efficiencies of vector-free human iPSCs with an episomal approach. This simplified E8 medium should facilitate both the research use and clinical applications of human ESCs and iPSCs and their derivatives,and should be applicable to other reprogramming methods.
Non-integrating episomal plasmid-based reprogramming of human amniotic fluid stem cells into induced pluripotent stem cells in chemically defined conditions.
Cell cycle (Georgetown,Tex.) 2016 JAN
Abstract
Amniotic fluid stem cells (AFSC) represent an attractive potential cell source for fetal and pediatric cell-based therapies. However,upgrading them to pluripotency confers refractoriness toward senescence,higher proliferation rate and unlimited differentiation potential. AFSC were observed to rapidly and efficiently reacquire pluripotency which together with their easy recovery makes them an attractive cell source for reprogramming. The reprogramming process as well as the resulting iPSC epigenome could potentially benefit from the unspecialized nature of AFSC. iPSC derived from AFSC also have potential in disease modeling,such as Down syndrome or $\$-thalassemia. Previous experiments involving AFSC reprogramming have largely relied on integrative vector transgene delivery and undefined serum-containing,feeder-dependent culture. Here,we describe non-integrative oriP/EBNA-1 episomal plasmid-based reprogramming of AFSC into iPSC and culture in fully chemically defined xeno-free conditions represented by vitronectin coating and E8 medium,a system that we found uniquely suited for this purpose. The derived AF-iPSC lines uniformly expressed a set of pluripotency markers Oct3/4,Nanog,Sox2,SSEA-1,SSEA-4,TRA-1-60,TRA-1-81 in a pattern typical for human primed PSC. Additionally,the cells formed teratomas,and were deemed pluripotent by PluriTest,a global expression microarray-based in-silico pluripotency assay. However,we found that the PluriTest scores were borderline,indicating a unique pluripotent signature in the defined condition. In the light of potential future clinical translation of iPSC technology,non-integrating reprogramming and chemically defined culture are more acceptable.
