Human pluripotent stem cells (hPSCs) have the ability of indefinite self-renewal and to differentiate into all types of human adult cells.

The Laslett group investigates the biology of human pluripotent stem cell lines, including embryonic stem cells (hESC) and human induced pluripotent stem cells (iPS) – developed cells that have been manipulated to enter a more primitive, less specialised stem cell state.

Research

More understanding of human pluripotent stem cell lines will lead to the development of tools and novel cell lines that will be required for the safe use of these cell types in future cell-based industries.

This is important because although the potential for the treatment of diseases and injuries is huge, the technology also creates a number of risks when producing cell populations to be used for cell therapy.

  • The production and characterisation of monoclonal antibodies that detect live human pluripotent stem cells
  • Functional uses for monoclonal antibodies that detect live human pluripotent stem cells
  • The development of “disease in a dish” models using human induced pluripotent stem cells
  • Investigation of culture substrates for the maintenance and differentiation of human pluripotent stem cells.
