Аннотация
BACKGROUND: Diabetes mellitus is related to wound healing process impairments and molecular abnormalities of the wound. We aimed to evaluate the therapeutic potential of semi-solid bone marrow as a source of stem cells (SCs) in regenerative medicine.
METHODS: This trial study was conducted at the Faculty of Medicine, Lorestan University of Medical Sciences, Khorram Abad, IRAN in 2019. Forty five Albino Wistar rats with an average weight of 250-300g, were purchased from Lorestan Aftabavaran Company in (Khorramabad, Lorestan, Iran). The rats were divided into 3 groups (n=15). For all groups, Streptozotocin (STZ) (Single dosage; 65 mg/kg, i.p.) was used to induce diabetes, and Sharp dissection was used to draw and pull down a dorsal skin flap (9×3 cm) in the control and saline groups on day0, respectively. The group used 7 × 109 BMMSCs on day 0. Histologic specimens were stained with hematoxylin and eosin and were stained with trichrome mason. Biomechanic measurements were taken in the wound area.
RESULTS: The epidermal thickness was increasing and blood vessels were growing. In the cells group, hair follicle destruction, cellular penetration, diffuse fibrosis, and necrosis were not observed in comparison with the saline and control groups. The Cells group had a higher energy absorption than the Bending stiffness and Maximal Force Ultimate Tensile Strength (UTS) group on day 14 as a result of decreased Bending stiffness and Maximal Force Ultimate Tensile Strength (UTS).
CONCLUSION: According on result of recent study, Stem cells can improve the healing of diabetic incision wounds.
