Wound management and wound dressing are significant functions of wound healing. A hydrocolloid film composed of a natural polymer such as carboxymethyl chitosan (CMCS) is a good candidate for use in the treatment of low exudate wounds such as superficial and black/grey necrotic wounds. The hydrocolloid film can be easily removed from a wound and promotes tissue granulation. In recent years, concerns have arisen regarding the existence of harmful chemical substances in products that come into direct contact with human skin. Therefore, natural substances are an exceptional choice. Due to their antibacterial properties, tea tree oil (TTO) and its active components have found uses in various applications, e.g. cosmetics, wound care, and food packaging. However, TTO has major drawbacks due to its high volatility and poor solubility in water as well as other polar solvents. Cyclodextrin is an ideal choice for enhancing its water solubility while preserving its antibacterial characteristics by utilizing the formation of an inclusion complex (IC) with certain TTO components. Various techniques have been utilized to examine the obtained ICs, i.e. GC-MS, UV–vis, 1H NMR, DSC, TG/DTG, FTIR, Zeta-sizer, and SEM. Moreover, molecular docking was employed to examine the preferred orientation of terpinene-4-ol within the cyclodextrin cavity.

The current treatments for endometrial injury offer limited clinical benefits and cannot improve endometrial receptivity and pregnancy outcomes. Stem cell therapies, or regenerative medicine, are considered potential solutions to address this concern and may offer effective treatment methods for the regeneration of thin endometrium. This study spots light on a combined therapeutic approach conjoining vasculogenesis, angiogenesis, proliferation, and remodelling of cells of the uterine endometrium studied in Wistar albino rat models. The ultimate objective of this research was to regenerate the thin endometrium using commercially obtained bone marrow derived rat mesenchymal stem cells with hormone 17-beta estradiol incorporated into a thermosensitive injectable hydrogel PluronicF127 by a novel minimally invasive intrauterine approach, ensuring a controlled release of hormone estradiol from the hydrogel invitro and the delivery of stem cells to regenerate the thin endometrium. Combining the proven ability of the hydrogel PF127, oestradiol, and rat mesenchymal stem cells to regenerate the endometrial basalis layer and Functionalis layers by inducing vascularization & angiogenesis, subsequently triggering the endometrial stem cells residing in the basalis layer. The injectable hydrogel (PluronicF127) showed satisfactory biocompatibility when loaded with oestradiol and rat mesenchymal stem cells. A thin endometrial rat model was established using 1 % Lugol's iodine rather than the traditional ethanol-induced method with the concept to preserve the endometrial basalis layer. The treatment with rat mesenchymal stem cells and oestradiol-loaded injectable hydrogel significantly enhanced the thickness of the endometrium and increased the abundance of blood vessels and glands in the injured endometrium compared to the control group. The rat mesenchymal stem cells and oestradiol-loaded injectable hydrogel treatment significantly reduced endometrial fibrosis; collagen deposits and increased the presence of endometrial glands. Endometrial thickness, angiogenesis, and molecular markers were assessed at 14- and 21-days post-treatment. Histological analysis revealed that PF127/E2/rMSCs significantly improved endometrial thickness, gland density, and vascularization compared to other groups. The PF127/E2/rMSCs group showed a significant decrease in collagen deposits, which Masson's trichrome staining confirmed. Angiogenesis markers (VEGFA, EGF) and genes linked to stem cells (SOX9, AXIN1, SSEA1) were found to be upregulated in molecular analysis, indicating increased vascularization and stem cell activation in the endometrial basalis layers.
