The ES/iPS cell facility at CRTD provides the following services:

Generation and characterization of induced pluripotent stem cells

The facility generates integration/transgene free human induced pluripotent stem (hiPS) cells from diverse kinds of somatic cells including, but not limited to, cells from cord and peripheral blood, various fibroblasts, brain endothelial cells.

The generated iPSCs are characterized for pluripotency using the following assays:

  • FLOW analysis of pluripotency markers
  • Quantitative real time PCR analysis of pluripotency markers
  • Quantitative real time PCR analysis of spontaneous and/or cytokine/growth factor assisted in vitro three germ layer differentiations
  • Short Tandem Repeat (STR) analysis
  • Karyotyping
  • Immunocytochemistry of Pluripotency markers
  • Immunocytochemistry of three germ layer markers
  • Mycoplasma testing
  • Post Thaw viability

The user of the facility chooses the number/level of characterization.

Engineering of hES/hiPS cell lines

This service includes the following:

  • Generation of isogenic hES/hiPS cell lines
  • Gene knock in/out in hES/hiPS cell lines
  • Gene/tissue specific single/double hES/hiPS cell reporters (fluorescencent and/or drug resistant)
  • Seamless gene corrections of point or short mutations in ES/iPS cell lines

Generation of cortical neural precursor cells (NPCs) from hES/hiPS cells

The facility helps optimize protocols and generates NPCs from hES/hiPS cells and provides them as frozen stocks to investigators. These NPCs can be plated in neuronal differentiation media giving rise to cortical neurons of upper and lower cortical layers.

Culture and adoption of hES/hiPS cells

  • The facility can develop feeder independent cultures of hES/hiPS cells from feeder dependent cultures to substrates like Matrigel, Vitronectin, Geltrex, and Synthamax. The adoption will include not only substrate adoption but also changing/adopting of media for support and maintenance of these lines on the adopted substrates.
  • hES/hiPS cell lines can be made to adapt to single cell passaging (TrypLe) on feeder or feeder independent cultures on Matrigel, Vitronectin, Geltrex, and Synthamax substrates.
