Dr Robin Lovell-Badge is Head of the Division of Stem Cell Biology and Developmental Genetics at the MRC National Institute for Medical Research in London, UK. His research group is interested in how stem cells differentiate into the specialised cells of the testis or ovary during embryonic development. The group also studies stem cell types, including pluripotent stem cells from very early embryos (ES cells) or after reprogramming from adult cells (iPS cells), and multipotent stem cells from the developing and adult central nervous system and pituitary. Certain genes are critical for self-renewal and to confer potential to stem cells. The Lovell-Badge lab explores how these genes impact on cell fate choices, and how they might be exploited to aid the treatment of a range of clinical problems, such as stroke and cancer.
