BDNF Increases Survival and Neuronal Differentiation of Human Neural Precursor Cells Cotransplanted with a Nanofiber Gel to the Auditory Nerve in a Rat Model of Neuronal Damage

Table 1

Animal groups. Group 1 (; survival time 3 weeks) had HNPCs injected to the AN with PA gel applied on the injection site. Group 2 (; survival time 3 weeks) had HNPCs injected to the AN with PA gel including BDNF applied on the injection site. Group 3 (; survival time 6 weeks) had HNPCs injected to the AN with PA gel with BDNF applied on the injection site. Group 4 was the control group (; 3-week survival time) and had medium only without cells injected to the nerve.
