A tetrapeptide regulator of hematopoiesis
Goralatide is a tetrapeptide regulator of hematopoiesis.1 It decreases the proportion of mouse high proliferative potential colony forming cells (HPP-CFCs) in S phase when cultured using regenerating femoral marrow conditioned medium at a concentration of 1 ng/ml. Goralatide (4 µg/kg twice per day) reduces decreases in the number of HPP-CFCs, burst-forming unit erythroid (BFU-E) cells, and colony forming unit granulocyte-macrophages (CFU-GMs) induced by 5-fluorouracil in mice.2 It also reduces mortality induced by doxorubicin in mice.3
