This podcast explores how
researchers are working on generating blood from a patient's skin
cells for optimal
stem cells therapy.
When you listen, you'll learn
- How blood stem cells are produced in our own body and reside in bone marrow before responding to signals to form progenitor cells that will differentiate,
- What steps Dr. Sugimura is taking to create Induced Pluripotent Stem Cells (IPS), and
- What ingredients are still missing from these IPS cells and how Dr. Sugimura thinks they will be able to solve these issues.
Rio Sugimura is a Research
Fellow at Boston Children’s Hospital with the Daley Lab working on
producing lab-grown blood.
First he explains our body's process for making blood, detailing
the importance of bone marrow as the home for blood stem cells that
generate all types of blood cells in our body. Along the way, he
explains the benefits of gene editing and different means of stem
cells therapy.
Specifically, he is using skin
cells instead of bone marrow to generate blood stem cells. He
explains the challenges this process presents compared to our
natural system and provides two essential categories in which the
IPS cells lack the same efficacy.
Specifically, these lab-generated IPS cells lack components of
genetic regulators that tell the cells how to behave and also lack
the environmental benefit a home of bone marrow provides. However,
he is working on solutions for these issues, including efforts
toward manufacturing bone marrow organoids.
He finishes by explaining the next steps in developing and testing
how these cells will work in bodies and how this exploration works
in tandem with benefits of gene editing.
