The Human Cells, Tissues, and Organoids (HCTO) Core strives to make research using human pluripotent stem cells and their derivatives accessible to all researchers.

Services Offered

Tissue Culture Facilities for Rent

Access to biosafety cabinets, a clean bench, incubators, microscopes, and all other equipment necessary for the culture of human pluripotent stem cells under a Core ESCRO protocol

Group and Individual Training

Multiple small group, hands-on classes are offered every year on the culture of human pluripotent stem cells, and their differentiation into various lineages (e.g. neural differentiation). Custom individual training is also available.

Human Embryonic Stem Cell Lines and Differentiated Cells

NIH-approved hESC lines (H1, H9), as well as differentiated cell types (e.g. neural progenitors, cardiomyocytes, astrocytes, etc)

Custom Workflows

Contact the Core directly to inquire about custom experimental workflows and differentiation schemes
