Methods. For multipart research comparison, human BM HDODs-, healthy donor-derived, umbilical cord blood nuclear cells, or CD34+ cells were transplanted into sublethally irradiated NOD/SCID mice. Twenty-eight days after transplantation nuclear cells were isolated from the murine BM, spleen, and peripheral blood and were used to quantitatively detect human CD45 antigen by quantitative real-time reverse transcriptase–polymerase chain reaction and flow cytometry. The clonogenic growth of human colony-forming units was also investigated.
Results. We found that umbilical cord blood-derived HSPCs showed the greatest transplantation potential in our in vivo model. Interestingly, the transplantation potential of HSPCs collected from the BM of HDODs was of the same quality as cells obtained from healthy BM donors.
Conclusion. Based on these results, we conclude that HDODs are a strongly underappreciated source of HSPCs that are ready to use for clinical purposes (read more). Print this post
I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the
ReplyDeleteliver already present. I started on antiviral medications which
reduced the viral load initially. After a couple of years the virus
became resistant. I started on HEPATITIS B Herbal treatment from
ULTIMATE LIFE CLINIC (www.ultimatelifeclinic.com) in March, 2020. Their
treatment totally reversed the virus. I did another blood test after
the 6 months long treatment and tested negative to the virus. Amazing
treatment! This treatment is a breakthrough for all HBV carriers.
