Antiapoptotic and proliferative selection pressures subjected to cells in culture can lead to the accumulation of genetic and epigenetic changes, which promote a phenotype analogous to that of a tumour cell. This process of culture adaptation is fully discussed in Section 1.3, but it should be noted that such changes present a significant barrier to the successful application of hPSCs in tissue engineering. If an adapted cell of this type were to be implanted into a person, there would be a significant danger of tumour formation. For this reason, any cell population that is used for such a purpose needs to undergo a thorough genetic analysis of the kind described in Section 1.3.
