ABSTRACT

BACKGROUND:

Choosing an effective means to label and trace the distribution, differentiation and migration of celsin vivo help to further explore the specific mechanism of cels that exert a therapeutic effect.

OBJECTIVE:

To understand the migration and localization of BrdU-labeled human umbilical cord mesenchymal stem cels in brain injury model rats.

METHODS:

Human umbilical cord blood samples were obtained, and the isolation of human umbilical cord mesenchymal stem cels was carried out. The primary and passage culture were performed. The phenotype of cels was detected by flow cytometry. Passage 3 human umbilical cord mesenchymal stem cels were labeled using BrdU, and the cel proliferation was detected using MTT method. BrdU-labeled cels were injected into brain injury ratsvia the tail vein. At 14 days after transplantation, brain tissues in the injury region were cut into sections and the migration and location of the umbilical cord mesenchymal stem cels were observed under inverted fluorescence microscope. RESULTS AND

CONCLUSION:

Cel surface specific markers CD45 and CD34 were detected by flow cytometry, but the cels could not express CD44, CD105 and CD29. Based on the cel growth curve, the cels came into a conditioning period at 1-3 days of seeding and came into a logarithmic phase at 3-5 days. BrdU-positive cels were visible at the injury region after 14 days, indicating that in the rats, transplanted human umbilical cord mesenchymal stem cels migrated from the peripheral blood to the site of brain injury to achieve the effective repair of injured parts.
