MUTATED HUMAN EMBRYONIC STEM CELLS FOR THE STUDY OF HUMAN GENETIC DISORDERS

Most cases of colorectal cancer (CRC) are initiated by inactivation mutations in the APC gene, which is a negative regulator of the Wnt-β-catenin pathway. Patients with familial adenomatous polyposis (FAP) inherit a germline mutation in one APC allele, and loss of the second allele leads to the deve[r]

free mouse embryonic stem cells. Parallel activity of STAT3 andSmad leads to inhibition of differentiation programs induced by theother pathway, thereby upholding the pluripotent state of the cells.The balance is easily broken upo[r]
