What are you looking at?
These are fibroblasts - cells grown from a small skin biopsy.
Fibroblasts are naturally found in skin and connective tissue. In the lab, our team carefully grows and expands these cells, creating enough to move forward to the next steps of the process.
Why do they matter at HeartWorks?
These fibroblasts can be reprogrammed into induced pluripotent stem cells (iPSCs,) cells that have the ability to become many different cell types. From there, we can guide them to become cardiomyocytes, the muscle cells that make the heart beat.
So while this microscope image may look like a dish full of cells, it represents an important early step in a much bigger process:
Skin biopsy → fibroblasts → iPSCs → heart cells.
