Meanwhile, in comparison to the control group, GHK-Cu accelerated the regeneration of nerve fibers from nerve stubs placed in a collagen tube, increased the number of axons and the proliferation of Schwann cells, and boosted the synthesis of nerve growth factor and the neurotrophins NT-3 and NT-4 [23]
These studies showed that NMN did not interfere with the doseresponse curves of the chemotherapy agents bleomycin, cisplatin, doxorubicin, etoposide, gemcitabine, methotrexate, paclitaxel, or vincristine, using in vitro cell viability (crystal violet staining) as a readout for their efficacy (Fig

Studies examining long-term neuroplasticity, neuroprotection, or recovery from injury more frequently employ every-other-day or three-times-weekly schedules, recognizing that structural brain changes require time to develop and may benefit from pulsed rather than continuous stimulation
