Human pluripotent stem cells (hPSCs) acquire changes at the genomic level upon proliferation and differentiation (Peterson and Loring, 2014). Studies from International Stem Cell Initiative and independent laboratories identified a copy number variant (CNV) in hES cell lines displaying a normal karyotype, which provided a selective advantage to hES cells in culture. In our laboratory we have identified variant H9-hESC (derived from H9-hESC) with normal karyotype, pluripotency expression, differentiation profile but with altered traits of high cell survival and low E-CADHERIN expression.

Interestingly, both the molecular basis of MBC and its histological profile are often quite distinct from the far more prevalent female breast cancer, emphasizing the need for increased focus on MBC. Here, we present a case report of an MBC patient from India with a strong familial history of breast cancer.

Abnormalities of secondary sexual differentiation manifest in varying degrees depending upon the severity of the underlying cause. Primary amenorrhea in phenotypic females is caused by several different factors, including hormonal imbalance, nutritional deficiency and sex differentiation abnormalities. Androgen insensitivity syndrome (AIS) accounts for a large proportion of such cases in phenotypic females but genetically male individuals.
