Cryopreserved allogeneic mesenchymal stem cells enhance wound repair in full thickness skin wound model and cattle clinical teat injuries. Curr Res Transl Med 2022; 70:103356. [PMID: 35940080 DOI: 10.1016/j.retram.2022.103356] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 05/16/2022] [Accepted: 06/02/2022] [Indexed: 01/31/2023]
Abstract
The study was aimed to evaluate and compare the healing potential of mesenchymal stem cells (MSCs) derived from two common sources (iliac crest derived bone marrow and omental fat) in a full thickness skin wound model. Bone marrow derived MSCs clinical efficacy in the repair of cattle teat fistulae (cutaneous and muco-cutaneous wounds) was also evaluated. In a completely randomized placebo controlled experimental full thickness skin wound model, n=36 were randomly divided into three equal groups: groups I, II and III receiving Phosphate buffered saline (PBS), BM-MSCs and adipose tissue MSCs (AD-MSCs), respectively. Grossly early reduction in inflammation and enhanced epithelialization in the cell-treated groups as compared to the control was seen. Microscopy, ultramicroscopy, gene expression analysis and mechanical testing revealed better and early matrix formation with a reduced scar formation and a higher tensile strength in the cell-treated groups as compared to the control. An overall comparable healing in the cell treated groups was observed, although BM-MSCs had led to the better matrix formation tending to scarless healing while the AD-MSCs had led to the early wound closure with a good tissue strength. In the case controlled bovine clinical teat injuries study (n=17) repaired surgically, BM-MSCs (n=13) or PBS (n=4) was injected locally. In surgico-MSCs treated cases, 84.6% non-recurrence rate was observed as compared to the 50% seen in the control. It was concluded that MSCs irrespective of the donor tissue have potential to improve healing of full thickness cutaneous wounds and/ fistulae.

Abstract
AIMS To compare stainless steel staples and polypropylene suture material for primary closure of wounds after teat amputation in ewes and to assess progress of healing in the presence or absence of intramammary infection (IMI). METHODS Chios-cross ewes, aged 3-5 years were randomly allocated to be infected in one teat with 1,200-1,500 cfu of Mannheimia haemolytica 5 days after parturition (groups A and B; n = 8 in each group) or remain uninfected (groups C and D; n = 4 in each group). On the following 4 days one teat from each ewe was amputated 2.5 cm from the teat end and the wound was closed using skin staples (groups A and C) or polypropylene sutures (groups B and D). Clinical evaluation of wound healing was performed between 1-21 days after surgery. On day 21 tissue sections were collected for tensiometric and histological evaluation. RESULTS The mean interval from the start to finish of wound closure was shorter when staples were used than when sutures were used (p < 0.001). Healing scores were lower (improved) for ewes in group A than B between days 1-7 after surgery (p = 0.005), but were similar between days 10-21 (p = 0.43). Healing scores were similar in groups C and D (p = 0.98). The tensile strain at maximum load was higher in tissue from group A than B (p = 0.001) and D (p = 0.004), but all other tensiometric measures were similar between groups. Histologically, collagen density was higher in sections from group A than B (p = 0.05) and D (p = 0.01), and angiogenesis was lower in sections from group A than B (p = 0.03) and D (p = 0.01). CONCLUSIONS AND CLINICAL RELEVANCE Skin staples and polypropylene sutures can be used effectively for primary closure of teat wounds, even in the presence of IMI. Skin staples had the advantage of a reduction in surgical time. ABBREVIATION IMI: intramammary infection.

Abstract
OBJECTIVE Evaluation of use of a supernumerary teat as a pedicle graft to repair experimental teat tip damage in cattle. STUDY DESIGN Experimental study. ANIMALS Mature, non-gravid hybrid cows with > or =1 supernumerary teat. METHODS The main teat and adjacent supernumerary teat were examined for patency by ultrasound with a 8 MHz linear array transducer. The tip of the main teat was resected at the junction of cistern and canal. The supernumerary teat was partially resected semi-circumferentially at the cranial aspect of the base to maintain vascular supply and transplanted by end-to-end anastomosis. The pedicle of the supernumerary teat graft was amputated in stages starting at 14 days, again at 16 days and separated at 18 days. Reconstructed teat patency was evaluated at intervals by ultrasonography and confirmed at 50 days by histopathology. Repeated measures ANOVA was used to compare the measurements of luminal diameter between days; significance was set at P<.05. RESULTS All reconstructed teats were patent. Decreased luminal diameters were detected at 25, 32, 39, and 46 days by ultrasonography. On histopathology, granulation and epithelial (mucosal) proliferation contributed to luminal reduction. CONCLUSIONS In this experimental model of an acute damage to a teat tip, supernumerary teat grafting was successfully used to restore teat anatomy. CLINICAL RELEVANCE Supernumerary teat pedicle grafting may be considered as a salvage technique for reconstruction of a damaged bovine teat in cows that have an adjacent patent supernumerary teat. Function of the reconstructed teat in a lactating cow remains unknown.

Abstract
Injuries to the end of the teat are frequent and frustrating to treat. Treatment of these injuries evolved from being aggressive using teat knives to a more conservative approach employing rest nonreactive teat inserts. The process of milking seems simple, but it involves fine-tuned mechanics. Teat fibrosis, even when small, has a disastrous effect on the production life of an animal. There is no place for error; any surgical intervention should be precise and aim for perfection. Medical imaging techniques and minimally invasive surgery help the surgeon to make the best decision. Finally, more investigation is needed to treat varicose veins to understand the origin and develop better treatment. Teat injuries have drawn more attention more recently. Surgical interventions are better planned, and blind treatment with unsuitable teat knives is avoided. Treatment of superficial of full-thickness teat lacerations does not require a high level of anatomic or surgical knowledge, although basic surgical principles should be applied. Hemostasis, delicate débridgement and tissue handling, and appropriate suture materials and patterns are key to success. Appropriate sedation, anesthesia, and analgesia are essential to achieve this goal and should never be neglected.

Abstract
Injuries to the teat in dairy cows can result in partial or complete obstruction of the teat lumen. Different treatment techniques have been used to restore normal function in injured teats, one of which is autogenous mucosal grafts. The purpose of this study was to evaluate the vestibular mucosa as a replacement for teat mucosa in severe teat injuries. Sixteen teats of four healthy, mature, non-gravid Jersey cows were randomly divided into two equal groups. Under high epidural analgesia and after surgical preparation a 1 x 1.5 cm piece of teat mucosa was removed. In group 1, the defect was replaced by a 2 x 2.5 cm vestibular mucosa, whereas in group 2, the defect was left open. In both groups, a sterile disposable teat cannula was inserted into the teat cistern following surgery. To evaluate luminal diameter, double contrast radiography with constant air pressure was performed every 25 days till day 125, after which the animals were slaughtered and teats removed for histopathological study (H&E staining). On the basis of radiographic examination, luminal narrowing in group 2 was significantly more severe than in group 1. Histopathologically, the entire mucosal grafts of group 1 were taken and a good adhesion could be seen between the graft and the host epithelium. In group 2, severe submucosal fibrosis and mucosal papilloid hyperplasia resulted in severe narrowing of the teat cistern. According to the results of this study, it can be concluded that using vestibular mucosal grafts with temporary insertion of teat cannula can be considered as a method of treating teat mucosal injuries.
