What are human embryonic stem cells?
Human embryonic stem cells are pluripotent cells that can differentiate into any cell type in the body.
Why are feeder cells used in stem cell culture?
Feeder cells provide essential growth factors and a supportive environment for stem cells to thrive.
What is matrigel?
Matrigel is a gelatinous protein mixture that mimics the extracellular environment, supporting cell growth.
How can hESCs be maintained in a pluripotent state?
By using appropriate culture conditions, including specific media and substrates like MEF or matrigel.
What is the significance of this procedure?
This procedure is crucial for researchers working on regenerative medicine and stem cell therapies.
