Pakpoom Kheolamai earned his M.D. (first class honours) from Chulalongkorn University in 2002. After received his medical degree, he went on to pursue his Ph.D. by studying the mechanisms underlying the differentiation process of mouse embryonic stem cells toward hepatocytes with Professor Alan Dickson at Faculty of Life Sciences, University of Manchester. After received his Ph.D. in 2006, he went back to Thailand to take a position as a lecturer, and then assistant professor at Division of Cell Biology, Faculty of Medicine, Thammasat University (Thailand). During this time, he has closely collaborated with Prof. Surapol Issaragrisil from Faculty of Medicine Siriraj hospital, Mahidol University, in studying the biology and clinical applications of various adult stem/progenitor cells. In 2010, he became a member of the newly established SiSCR where he continued his stem cell research. His recent work focuses on the biological properties of endothelial progenitor cells (EPCs) regarding their founding population, the factors that are required to induce their proliferation and differentiation as well as their roles in vascular homeostasis and vascular diseases. He also studies the biology of mesenchymal stem cells derived from both bone marrow and gestational tissues regarding their proliferation capacity, differentiation potential, immunomudulatory property and their clinical applications.
