Overview

Human embryonic stem (ES) cells are routinely passaged as clumps, rather than single cells. To generate clumps appropriate for passaging, both enzymatic and mechanical (by dissection or scraping) methods can be used. Collagenase Type IV is an enzyme that is routinely used at 1 mg/mL for the generation of human ES cell and iPS cell clumps for passaging.

Enzymatic

A Concise Protocol for siRNA-Mediated Gene Suppression in Human Embryonic Stem Cells. Renz PF and Beyer TA Methods in molecular biology (Clifton, N.J.) 2016 FEB

Abstract

Human embryonic stem cells hold great promise for future biomedical applications such as disease modeling and regenerative medicine. However, these cells are notoriously difficult to culture and are refractory to common means of genetic manipulation, thereby limiting their range of applications. In this protocol, we present an easy and robust method of gene repression in human embryonic stem cells using lipofection of small interfering RNA (siRNA).
Aneuploidy induces profound changes in gene expression, proliferation and tumorigenicity of human pluripotent stem cells. Ben-David U et al. Nature communications 2014 SEP

Abstract

Human pluripotent stem cells (hPSCs) tend to acquire genomic aberrations in culture, the most common of which is trisomy of chromosome 12. Here we dissect the cellular and molecular implications of this trisomy in hPSCs. Global gene expression analyses reveal that trisomy 12 profoundly affects the gene expression profile of hPSCs, inducing a transcriptional programme similar to that of germ cell tumours. Comparison of proliferation, differentiation and apoptosis between diploid and aneuploid hPSCs shows that trisomy 12 significantly increases the proliferation rate of hPSCs, mainly as a consequence of increased replication. Furthermore, trisomy 12 increases the tumorigenicity of hPSCs in vivo, inducing transcriptionally distinct teratomas from which pluripotent cells can be recovered. Last, a chemical screen of 89 anticancer drugs discovers that trisomy 12 raises the sensitivity of hPSCs to several replication inhibitors. Together, these findings demonstrate the extensive effect of trisomy 12 and highlight its perils for successful hPSC applications.
Trisomy 21 mid-trimester amniotic fluid induced pluripotent stem cells maintain genetic signatures during reprogramming: implications for disease modeling and cryobanking. Pipino C et al. Cellular reprogramming 2014 OCT

Abstract

Trisomy 21 is the most common chromosomal abnormality and is associated primarily with cardiovascular, hematological, and neurological complications. A robust patient-derived cellular model is necessary to investigate the pathophysiology of the syndrome because current animal models are limited and access to tissues from affected individuals is ethically challenging. We aimed to derive induced pluripotent stem cells (iPSCs) from trisomy 21 human mid-trimester amniotic fluid stem cells (AFSCs) and describe their hematopoietic and neurological characteristics. Human AFSCs collected from women undergoing prenatal diagnosis were selected for c-KIT(+) and transduced with a Cre-lox-inducible polycistronic lentiviral vector encoding SOX2, OCT4, KLF-4, and c-MYC (50,000 cells at a multiplicity of infection (MOI) 1-5 for 72 h). The embryonic stem cell (ESC)-like properties of the AFSC-derived iPSCs were established in vitro by embryoid body formation and in vivo by teratoma formation in RAG2(-/-), $\$-chain(-/-), C2(-/-) immunodeficient mice. Reprogrammed cells retained their cytogenetic signatures and differentiated into specialized hematopoietic and neural precursors detected by morphological assessment, immunostaining, and RT-PCR. Additionally, the iPSCs expressed all pluripotency markers upon multiple rounds of freeze-thawing. These findings are important in establishing a patient-specific cellular platform of trisomy 21 to study the pathophysiology of the aneuploidy and for future drug discovery.
