The planarian Schmidtea mediterranea. Credit: A. Sánchez Alvarado.
The PTEN molecules were originally identified and characterized in the laboratory of Dr. Alejandro Sanchez Alvarado, HHMI investigator and Professor of Neurobiology and Anatomy at the University of Utah School of Medicine. Dr. Sánchez Alvarado's is the paper's senior author. His laboratory is engaged in the identification of the molecular and cellular basis of animal regeneration. His laboratory's work on planarians has led to the establishment of this organism as an important model system to study stem cells, regeneration and tissue homeostasis. The Forsyth research team is led by Michael Levin, Ph.D., Senior Member of the Staff in The Forsyth Institute and the Director of the Forsyth Center for Regenerative and Developmental Biology. Through experimental approaches and mathematical modelling, Dr. Levin and his group examine the processes governing large-scale pattern formation and biological information storage during animal embryogenesis. The lab investigates mechanisms of signalling between cells and tissues that allow a living system to reliably generate and maintain a complex morphology. The Levin team studies these processes in the context of embryonic development and regeneration, with a particular focus on the biophysics of cell behaviour. ......... ZenMaster
