Combining cryopreserved autografts and vascularized bone flap for craniofacial defect reconstruction in fibrous dysplasia: a case report.

INTRODUCTION AND IMPORTANCE: Polyostotic fibrous dysplasia (PFD) is a rare, benign skeletal disorder characterized by the replacement of normal bone with fibro-osseous tissue. Craniofacial involvement often results in progressive deformities, functional impairments, and aesthetic concerns. Surgical intervention aims to remove diseased bone and restore structure and function, employing techniques like vascularized bone flaps, autografts, and cryopreserved bone. This report presents a case utilizing cryopreservation combined with vascularized fibula flap for craniofacial reconstruction. CASE PR…

Reconstruction of xenogeneic seminiferous tubule-like structures in mouse testis using cryopreserved rat testicular cells.

Spermatogonial stem cells sustain spermatogenesis within a Sertoli cell-organized niche, yet xenogeneic spermatogenic differentiation after transplantation into host mouse seminiferous tubules has been reported in only a limited number of donor species. Here, we tested whether host niche engineering could support xenogeneic spermatogenic differentiation. Immunodeficient mouse testes were preconditioned by busulfan-mediated germ cell depletion followed by intratubular benzalkonium chloride treatment to reduce Sertoli cells, and cryopreserved rat testicular cells were transplanted into the modif

A dual-drug strategy to enhance the function of cryopreserved ovaries by promoting revascularization and inhibiting follicle over-activation.

BACKGROUND: Ovarian tissue cryopreservation and transplantation (OTCT) is a promising approach for fertility preservation. However, significant follicle loss after transplantation challenges long-term reproductive recovery. Although primordial follicle loss and ischemic damage are known contributors, the underlying mechanisms and effective strategies to mitigate these damages are still lacking. METHODS: Ovarian tissues from wild-type or Tek-CreERT2;mTmG female mice were cryopreserved using vitrification. Follicle dynamics after OTCT were analyzed through histology, proteomics, and high-resolu…

Optimizing the cryopreservation and post-thaw recovery of natural killer cells is critical for the success of off-the-shelf platforms.

Natural killer (NK) cells are a promising allogeneic, off-the-shelf, cellular immunotherapy product. These cells can be manipulated ex vivo, genetically edited to enhance tumor targeting and expanded to produce large cell banks for multiple patient infusions. Therapeutic efficacy of these products depends on the recovery of viable and functional cells post-thaw. Post-thaw loss of viability and cytolytic activity results in large, and often variable, discrepancies between the intended cell dose (based on counts at cryopreservation) and the actual dose administered. Compared to their highly acti…

Role of cryopreserved multipotent mesenchymal stromal cells in modulation of some indices of cell immunity in adjuvant arthritis.

INRODUCTION: The results of experimental and clinical studies in recent years indicate that the transplantation of multipotent mesenchymal stromal cells (MMSCs) is a possible approach for the "restoration" of the immune system of patients with autoimmune diseases, in particular, rheumatoid arthritis. However, the strength and duration of the effect vary greatly, which indicates incomplete correction of the tested parameters, thereby opening up the prospect of improving this method of treatment by choosing dose-time parameters and methods of their administration. The aim of this research was to
