Barbara Corneo, PhD

Profile Headshot


Barbara manages the daily activity of the Columbia Stem Cell Core Facility, bringing her knowledge in stem cell research and enthusiasm for collaborating and teaching to serve the Columbia Stem Cell Community as well as external users. Barbara grew up in Italy and got a PhD in Immunology in Paris, France, working on severe combined immunodeficiency and V(D)J recombination. She then moved to the United States where she continued working on the effects that mutations in the Rag1 & 2 genes cause on the immune system. Barbara then joined Dr. Gordon Keller lab in Mount Sinai, where she learned the basis of hESC biology and worked on endoderm differentiation and specification toward hepatic and pancreatic progenitors. She then joined the Neural Stem Cell Institute, directed by Dr. Sally Temple, to learn more about the nervous system. She worked on iPSC derivation from human ocular tissues and differentiation of hESC and hiPSC into retinal pigment epithelium (RPE). Barbara now directs the Columbia Stem Cell Core Facility, to provide support and to offer her expertise and help to any user interested in learning more about adult stem cells, embryonic stem cells, induced pluripotent stem cells and their differentiated progenies.

Don't stop 'til you get enough

The Stem Cell Core Facility is a multi-center facility at Columbia University Medical Center, created to help users take advantage of up-to-date resources in the stem cell field in a timely and cost-efficient way.

The Columbia Stem Cell Core Facility has two primary aims:

To give our users access to quality-controlled pluripotent stem cells and stem cell-derivatives prepared using standardized approaches

To offer genome editing services for the generation of custom-designed cell lines

We are connected to Stem Cell COREdinates, a consortium of pluripotent stem cells-focused core facilities, which allows us to take advantage of the sharing of the most updated and efficient protocols, expertise, and reagents.
