Abstract:

Background: Equine wounds, particularly those involving the distal portion of the limbs, often undergo prolonged complex healing and may enter a non-healing state with obvious financial and welfare implications. Poor blood supply and lower levels of oxygen to the lower limbs lead to imbalance of growth factors related to wound healing. Decellular amniotic membrane has been widely used in soft tissue engineering especially skin regeneration due to its biological and mechanical properties. It is used as a scaffold for treatment of partial full thickness wound dressing. OBJECTIVES: Evaluation of the effects adipose derived mesenchymal cells (ADMSCs) cultured on decellularized amniotic membrane (DAM) in wound healing of distal part of equine limb. METHODS: Stem cells were isolated from adipose tissue in the base of the tail and then cultured and seeded on bovine decellular amniotic membrane. Full thickness excision wounds (2x3 cm) were created on the mid-lateral of all metatarsus of each horse aseptically. The wounds were classified into four groups: the first one covered by DAM seeded by ADMSCs, the second one dressed with only DAM, the third one treated with1% silver sulfadiazine, and the last one as control with no treatment. Digital photographs of wounds were obtained at each bandage change while biopsy samples were obtained for histopathology at days 5, 15 and 30 after treatment. RESULTS:Wounds treated with DAM/ADMSCs significantly demonstrated promotion of wound healing in geometric analysis of total wound area, epithelialization and wound contraction compared with the other groups (P
