Disorders in pulmonary vascular integrity are a prominent feature in many lung diseases. Paracrine signaling is highly enriched in the lung and plays a crucial role in regulating vascular homeostasis. However, the specific local cell-cell crosstalk signals that maintain pulmonary microvascular stability in adult animals and humans remain largely unexplored.

Umbilical cord blood (UCB) represents a valuable graft source in the absence of a human leukocyte antigen (HLA)-matched donor for hematopoietic cell transplantation (HCT). Donor-specific anti-HLA antibodies (DSAs), targeting grafts with mismatched HLA antigens, pose a significant obstacle by increasing the risk of primary graft failure, delayed engraftment, and decreased survival. Existing literature on HLA desensitization has primarily focused on haploidentical transplants, and there is a lack of experience regarding the optimal strategy in UCB transplantation.

Aims: The development and selection of T cells occur within the thymus. This organ involutes throughout life, compromising the generation of T cells and, consequently, the efficacy of the immune system. Mesenchymal stem cells (MSC) have beneficial effects on the immune system.

This study tested whether combined ceftriaxone and adipose-derived mesenchymal stem cells (ADMSCs) would defend the spinal cord against acute spinal infection (ASI) in rodent. Adult-Male-SD rats were grouped into groups 1 (SC)/2 (ASI)/3 (ASI + ceftriaxone from days 2 to 28 after ASI induction)/4 (ASI + allogenic ADMSCs from day 2 for a total of 3 doses/3 consecutive intervals by intravenous injection)/5 (ASI + combined ceftriaxone and ADMSC) and spinal cord tissues were harvested by day 28. Circulatory levels of TNF-α/IL-6 at days 7 and 28, and these two parameters in spinal fluid at day 28 were lowest in group 1, highest in group 2, significantly lower in group 5 than in groups 3/4, and significantly lower in group 3 than in group 4 (all p < 0.

Intravenous (IV) injection is widely recognized as the most effective and commonly utilized method for achieving systemic delivery of substances in mammalian research models. However, its application in adult zebrafish for drug delivery, stem cell transplantation, and regenerative and cancer studies has been limited due to the challenges posed by their small body size and intricate blood vessels. To overcome these limitations, alternative injection techniques such as intracardiac and retro-orbital (RO) injection have been explored in the past for stem cell transplantation in adult zebrafish.
