Regeneration is in essence the recapitulation of early development. The Sánchez Alvarado Lab investigates the genetic basis and molecular processes of regeneration and tissue maintenance. The group has established the planarian flatworm, Schmidtea mediterranea, as an essential research organism for regeneration science across the globe.
Dozens of genes, and genetic and molecular pathways that drive planarian regeneration have been uncovered in the lab. The lab has identified that adult somatic stem cells are the sole proliferating cell type that differentiate and are responsible for proper anatomical and functional integration of new tissues into pre-existing tissue.
The Sánchez Alvarado Lab continues to study planarians yet has expanded regeneration research to other organisms including the apple snail, Pomacia cannaliculata, and the African killifish, Nothobranchius furzeri. By investigating and characterizing the molecular and genetic basis of regeneration in multiple research organisms, the team seeks to understand developmental and evolutionary tradeoff mechanisms in higher organisms, including humans.
Principal Investigator
President and Chief Scientific Officer
Stowers Institute for Medical Research
Alejandro Sánchez Alvarado, Ph.D., is the President and Chief Scientific Officer of the Stowers Institute. Alejandro joined the Institute in 2011, was named its Scientific Director in 2019, and named Executive Director and Chief Scientific Officer in 2021. In 2023 he was named President and Chief Scientific Director.
Planarians are an excellent research organism for studies on regeneration. The Sánchez Alvarado Lab investigates the mechanisms underlying regeneration using both the asexual and sexual strains of the flatworm, Schmidtea mediterranea, and a newly discovered planarian isolate, Girardia sp. (Guanajuato).
Where would you be 20 years from now if you were to join Stowers? Executive Director and Chief Scientific Officer, Alejandro Sánchez Alvarado, explains how doing science here is different and why you should join our team.
Alejandro Sánchez Alvarado receives the Vilcek Prize in Biomedical Science for his contributions to the field of regeneration—from the identification of crucial genes that control regeneration in living organisms, to the potential for regenerative medicine to treat disease.
