Adipose-derived mesenchymal stromal cells: A study on safety and efficacy in ocular inflammation.

Purpose: This study explores the application of adipose-derived mesenchymal stromal cells (adMSCs) as a therapy for ocular inflammatory diseases utilizing a chronic GVHD model.

Methods: Human adMSCs were administered via subconjunctival injection into mice with chronic ocular GVHD. Clinical scores and changes in T cell populations were analyzed.

Cellular senescence promotes meibomian gland dysfunction in a chronic graft-versus-host disease mouse model.

Purpose: Aging is a well-established risk factor for meibomian gland dysfunction (MGD). We previously reported an accelerated cellular senescence phenomenon in the lacrimal glands of a murine model of chronic graft-versus-host disease (cGVHD). Herein, we aimed to elucidate the relationship between cellular senescence and MGD in cGVHD mice, utilizing the senolytic agent ABT-263.

MSCs Become Collagen-Type I Producing Cells with Different Phenotype in Allogeneic and Syngeneic Bone Marrow Transplantation.

Mesenchymal stem cells (MSCs) have been widely used in therapeutic applications for many decades. However, more and more evidence suggests that factors such as the site of origin and pre-implantation treatment have a crucial impact on the result. This study investigates the role of freshly isolated MSCs in the lacrimal gland after allogeneic transplantation.

Positive Effects of Oral Antibiotic Administration in Murine Chronic Graft-Versus-Host Disease.

Chronic graft-versus-host disease (cGVHD) is one of the most frequent complications experienced after allogeneic hematopoietic stem cell transplantation. Reportedly, dysbiosis and severe damage to the microbiome are also closely associated with GVHD. Herein, we aimed to elucidate the positive and negative effects of the administration of various antibiotics in a murine model of cGVHD.
