Abstract:

BACKGROUND: Combining Chinese medicine with stem cell transplantation opens up a new avenue for the use of traditional Chinese medicine in the stem cell transplantation. It is expected to improve survival and differentiation of cochlear stem cells into hair cells through Chinese medicine interventions.
OBJECTIVE: To observe the influence of Guiqi Dihuang Tang on the treatment of sensorineural deafness with cochlear stem cells.
METHODS: Guinea pigs with sensorineural deafness were randomly assigned into three groups: combined group intervened with cochlear stem cell suspension with medicated serum, cell transplantation group with cochlear stem cell suspension, and blank control group with normal saline injection. At 7, 28 and 56 days after treatment, all guinea pigs were detected for auditory brainstem response and immunofluorescent observation.
RESULTS AND CONCLUSION: Nestin positive cells and MyosinVIIA positive cells were observed in the combined and cell transplantation groups, and the number of positive cells was higher in the combined group than the cell transplantation group. Auditory brainstem response threshold of guinea pigs was decreased in the combined and cell transplantation groups, and the recovery of hearing was better in the former group. These findings indicate that the intervention of Guiqi Dihuang Tang can remarkably improve the survival rate of transplanted stem cells and the differentiation ratio of transplanted cells into hair cells.
