Hypothesis
Can CD34+ stem cells from umbilical cord blood differentiate into muscle cells and express dystrophin in vitro?
Conclusion
Umbilical cord blood CD34+ stem cells can interact with dystrophic muscle cells and restore dystrophin expression in vitro.
Supporting Evidence
- CD34+ stem cells fused with muscle cells immediately after co-culture.
- Differentiation into mature myotubes was observed after 15 days.
- Dystrophin-positive regions were detected through Immunofluorescence analysis.
Takeaway
Scientists found that special stem cells from umbilical cord blood can help muscle cells that are sick by making them produce a protein they need.
Methodology
CD34+ stem cells were isolated from umbilical cord blood and co-cultured with muscle cells from DMD patients to analyze differentiation and dystrophin expression.
Limitations
The expression of dystrophin observed was low and may not be sufficient for therapeutic applications.
Participant Demographics
CD34+ stem cells were obtained from healthy babies, and muscle cells were from DMD and DMB affected patients.
