Divya Nag (born c. 1991) is an American stem cell biologist, biotechnology entrepreneur, and a leader of Apple's Health and Research initiatives. At the age of 20, Nag co-founded Stem Cell Theranostics which uses patient-specific stem cells in a drug discovery platform.
Stem cell tourism is the part of the medical tourism industry in which patients travel to obtain stem cell procedures. [109] The United States has had an explosion of "stem cell clinics". [110] Stem cell procedures are highly profitable for clinics. The advertising sounds authoritative but the efficacy and safety of the procedures is unproven.
In 2012, stem cells were studied in people with severe heart disease. [48] The work by Bodo-Eckehard Strauer [49] was discredited by identifying hundreds of factual contradictions. [50] Among several clinical trials reporting that adult stem cell therapy is safe and effective, actual evidence of benefit has been reported from only a few studies ...
Limbal stem cell deficiency is one of the main causes of corneal blindness, which affects 6 million people worldwide. A novel type of stem cell treatment, however, appears to be a safe option for ...

Embryonic stem cells make up a significant proportion of a developing embryo, while adult stem cells exist as minor populations within a mature individual (e.g. in every 1,000 cells of the bone marrow, only one will be a usable stem cell). Thus, embryonic stem cells are likely to be easier to isolate and grow ex vivo than adult stem cells. [36]
He was on the cover of TIME magazine's "America's Best in Science & Medicine" feature in 2001 for his work with human embryonic stem cells, [12] and again in 2008 when the magazine named him one of the world's 100 most influential people for his derivation of human induced pluripotent stem cells.

Intestinal organoids have also been generated from intestinal stem cells, extracted from adult tissue and cultured in 3D media. [27] These adult stem cell-derived organoids are often referred to as enteroids or colonoids, depending on their segment of origin, and have been established from both the human and murine intestine.
