The Melero-Martin laboratory seeks highly motivated post-doctoral research fellows to investigate the mechanism by which vascular networks are formed from pluripotent stem cells and to develop novel approaches to therapeutic vascularization and tissue regeneration. We are also looking for candidates to study the use of fate-determining transcription factors to generate human vascular organoids.
Current NIH-funded (R01) projects at the Melero-Martin lab include:
Project 1 – Enhancing endothelial cell engraftment via transplantation of exogenous mitochondria. Goal: To dissect the mechanism by which mitochondria transfer renders cytoprotection in endothelial cells and to elucidate the role of autophagy and mitophagy upon the transfer of mitochondria.
Project 2 – Regulation of endothelial cell specification. Goal: To dissect the activity of the transcription factor ETV2 to drive endothelial cell specification in human pluripotent stem cells.
Project 3 – Vascular networks genetically engineered for protein drug delivery. Goal: To establish the feasibility of using bioengineered drug-secreting vascular networks to treat a clotting deficiency.
Project 4 – Human endothelial cell regulation of ossification. Goal: To elucidate the mechanisms by which blood vessels regulate the osteogenic activity of human mesenchymal stem cells and to develop new therapeutic strategies to regenerate bone.
All work will involve human stem cell culture, molecular biology, and mouse xenograft models.
