Alesha B. Castillo received her PhD in Biomedical Engineering from UC Davis in 2004. Her research is directed at elucidating molecular mechanisms by which mesenchymal stem cells sense and respond to mechanical and biochemical cues to regulate cell fate decisions. As individuals age, bones become less responsive to mechanical stimuli leading to bone loss and increased fracture risk. This may result from preferential differentiation of mesenchymal stem cells down the adipogenic versus osteogenic lineage during aging. The focus of Dr. Castillo’s SCL project was to better understand the basis for this lineage switch, knowledge that is key to developing novel therapeutic strategies for the prevention and treatment of osteoporosis and disuse bone loss.
