The wound healing process in rodents (rats and mice) and lagomorphs (rabbits) predominantly relies on wound contraction rather than re-epithelialization and granulation tissue formation. As a result, existing laboratory animal models for wound healing often fail to mimic human wound healing mechanisms accurately. This study introduces a standardized rabbit model with superior translational potential for skin wound healing research.

A contraction-suppressed full-thickness wound model was used to evaluate the therapeutic potential of Pluronic F127 (PF127) hydrogel loaded with adipose-derived stromal vascular fraction (AdSVF), mesenchymal stem cells (AdMSC), and conditioned media (AdMSC-CM) for the repair of wounds in a rabbit model. The experimental study was conducted on forty-eight healthy adult New Zealand white rabbits randomly divided into eight groups with six animals each and treated with AdSVF, AdMSC, and AdMSC-CM as an injectable or topical preparation.

The regenerative capacity of MSCs was evaluated in 40 rabbits divided into eight groups, four groups each for acute and subacute injury models. BM-MSCs and BM-MSCS-CM were prepared by isolating allogenic bone marrow from the iliac crest.

PRP is a class of liquid platelet concentrate containing a supra-physiological concentration of platelets in a relatively small amount of plasma. Its potential to heal various tissues has piqued interest in its therapeutic application as a biomaterial in regenerative medicine.

As such, multipotent adipose tissue-derived mesenchymal stem cells (AdMSCs), are one of the important components of AdSVF. Commonly used techniques to harvest AdSVF involve enzymatic or non-enzymatic methods.

Mammary gland affections are widespread, which affect the dairy industry economically and pose a potential public health hazard. Current therapeutic options are ineffective in controlling the infection and regenerating the gland effectively.

The present study was conducted to analyze the global trends in AdMSC research using bibliometric and visual analysis tools.
Methods: The literature search was done on February 13, 2022, using appropriate keywords and inclusion-exclusion criteria from the Scopus database.
Background And Aim: This work was conducted to compare the therapeutic potential of undifferentiated and osteogenic differentiated canine (xenogeneic) and guinea pig (allogeneic) BMSCs in fracture healing using guinea pig as a model.
Materials And Methods: A well-characterized homogenous population of third passage mesenchymal stem cells of bone marrow origin was used in all the experiments. MSCs from both the species, i.
A prospective clinical study consisting of six bovines (200-300 kg body weight) undergoing open tibial fractures was carried out, to evaluate the use of circular and hybrid external skeletal fixation (ESF) systems for open tibial fracture repair in large ruminants. The ESF systems consisting of 4 full rings (n = 2), 8 half-rings (n = 1), 2 full rings with 2 sidebars (n = 2) or 2 full rings with 4 sidebars (n = 1) were used to treat open tibial fractures. The healing progress of the animals was evaluated based on different clinical and radiographic examinations.

Platelet concentrates are broadly classified into two groups depending on their fibrin content, namely platelet-rich plasma (PRP) and platelet-rich fibrin (PRF). They are further divided based on their leucocyte contents.

Background: Bone grafting is a preferred treatment option for the healing of large diaphyseal bone defects and is useful in the management of nonunion, delayed union, and tumor resection.
Aims: To investigate a decellularization protocol of bovine cancellous bone for xenogenic implantation in radial bone defects in rabbits.
Methods: Bovine bone scaffolds fabricated with various decellularization protocols viz phosphate buffer saline (PBS), 1% sodium dodecyl sulfate (SDS), and rapid freeze and thaw technique.

Background: The wound healing potential of canine bone marrow-derived mesenchymal stem cells (BMSCs) was evaluated in the excisional wound of streptozotocin-induced diabetic rats.
Research Design And Methods: Xenogenic BMSCs were collected aseptically from the iliac crest of healthy canine donors under general anesthesia. Full-thickness experimental wounds (20 × 20 mm) on the dorsum of forty-eight adult healthy Wistar white rats.
Background And Aim: The currently available atrophic non-union models rely on wide segmental excision of bone diaphysis to impede the process of healing but lack resemblance to the clinical scenario. The present study focused on developing an model of atrophic non-union fracture in rabbit radius that can replicate the clinical scenario.
Materials And Methods: The atrophic non-union fracture model was developed by creating a 10 mm segmental bone defect in the radial diaphysis of five adult New Zealand White rabbits.
Background: Intervertebral disc herniation (IVDH) is one of the common causes of spinal cord injury (SCI) in dogs. It is commonly treated by performing surgical decompression that involves the removal of the extruded disc material. However, the recovery rates after surgical interventions are variable and many times unsatisfactory.

Mastitis (intramammary inflammation) caused by infectious pathogens is still considered a devastating condition of dairy animals affecting animal welfare as well as economically incurring huge losses to the dairy industry by means of decreased production performance and increased culling rates. Bovine mastitis is the inflammation of the mammary glands/udder of bovines, caused by bacterial pathogens, in most cases. Routine diagnosis is based on clinical and subclinical forms of the disease.
