In order to develop a stable supply of embryonic stem cell (ESC)-derived hepatocytes, we have purified human ESC-derived hepatic progenitor cells with exposure to cytocidal puromycin by using their ability to metabolize drugs. (bvsalud.org)
High drug-metabolizing hepatic progenitor cells can be matured into liver cells by suppressing hepatic proliferative signals. (bvsalud.org)

Numerous drugs that target RAS-related signaling pathways have been tested in patients with NF1 in phase I and phase II clinical trials, with disappointing results, hence the interest in selumetinib. (highlighthealth.com)
In phase I, we test the drug in healthy volunteers starting with very small doses followed by higher until the doses are expected to be effective in patients. (leo-pharma.com)
In phase II, the drug is tested in few patients and the effect on the target disease is evaluated. (leo-pharma.com)
