The Research Assistant (Islet Cell and Regenerative Biology) will work in a lab that studies biology and function of pancreatic islets including insulin secreting beta cells and glucagon-secreting alpha cells. The lab has recently started to work on adult tissue-specific stem cells, particularly those stem cells that form the pancreatic islet cells. Current topics under investigation include generation of induced pluripotent stem cells from mouse models of type 1 and type 2 diabetes and humans with type 1 and type 2 diabetes. The studies are focused on using peripheral tissues (e.g. skin fibroblasts, blood cells and adult skeletal or adipose tissues) to generate induced pluripotent stem (iPS) cells. Future studies will be focused on generating differentiated cells from these iPS cells, including pancreatic islet cells, mature skeletal muscle and adipocytes.
A research assistant is wanted to assist with ongoing experiments that include cell culture, molecular biology techniques, flow cytometry, histology, mammalian cell culture and animal studies, and banking of human and mouse iPS cells. The assistants responsibilities also will include maintenance of mouse colonies and genotyping of mouse strains. Some studies will involve collaboration with other investigators, and may require some assistance and work in these collaborators labs.
As a health care organization, we have the responsibility to do everything in our power to care for and protect our patients, our colleagues and our communities. Beth Israel Lahey Health requires that all staff be vaccinated against influenza (flu) and COVID-19 as a condition of employment.
