In another study, chitosan-coated Eudragit/Human Growth Hormone (hGH) nanofibrous sheets were prepared by electrospinning and dip-coating for oral mucositis, sheets incorporating hGH significantly increased the proliferation of human dermal fibroblasts, and in vivo studies in dogs showed that chitosan-layered sheets show accelerated wound recovery [129]. Here, GH1 is linked to oral mucositis.
