Clinical grade cultivation of human schwann cell by the utilization of human autologous serum instead of fetal bovine serum, and also avoiding any growth factors, can increase safety level of this procedure in cases of clinical cell transplantation. The aim of this study was demonstration of the feasibility of clinical grade schwann cell cultivation. In this experimental study after obtaining consent from close relatives we harvested 10 sural nerves from brain death donors and then cultured in 10 seperated culture media plus autologous serum. We also prepared autologous serum from donor's whole blood. Then cultured cells were evaluated by S100 antibody staining for both morphology and purity. Cell purity range was from 97% to 99% (mean=98.11 ± 0.782%). Mean of the cell count was 14,055.56 ± 2,480.479 per micro liter. There was not significant correlation between cell purity and either the culture period or the age of donors (P>0.05). The spearman correlation coefficient for the cell purity with the period or the age of donors was 0.21 and 0.09, respectively. We demonstrated the feasibility of clinical grade schwann cell cultivation by the using of human autologous serum instead of fetal bovine serum and also without the using of growth factors. We also recommended all cell preparation facilities to adhere to the GMP and other similar quality disciplines especially in the preparation of clinically-used cell products.

Background and objectives The persistent nature of diabetic foot ulcers (DFUs) is mainly attributable to compromised wound healing mechanisms, which are aggravated due to poor blood flow, neuropathy, and infection. Growth factors have become essential agents in the treatment of DFUs, serving as primary mediators that enhance wound healing through the stimulation of cell proliferation, migration, and angiogenesis. This prospective open-label, randomised, comparative, multi-centre, investigator-initiated study compared the safety and effectiveness of adjuvant therapy with topical application of autologous growth factor concentrate (AGFC) using the Healrex therapy kit (Wockhardt, India) versus standard of care (SoC) in DFUs.

Background: Chronic spontaneous urticaria (CSU) is a persistent skin condition with no known cause or trigger. The unpredictability of CSU attacks lowers patients' quality of life. NOD-like receptor pyrin domain containing 3 (NLRP3) gene dysregulation can result in numerous immunological and inflammatory diseases.

Objective: To observe the clinical efficacy of TPO receptor agonists and platelet transfusion in chemotherapy-induced thrombocytopenia in malignant tumors.
Methods: Clinical data from 120 patients with malignant tumors who developed thrombocytopenia following chemotherapy at our hospital were retrospectively collected and randomly divided into three groups: A, B, and C, with 40 patients in each group. Group A was treated with a TPO receptor agonist (avatrombopag), group B received autologous platelet transfusion, and group C received a combination of both treatments.

Purpose: To assess the impact of autologous serum (AS) tears at a 50% concentration on the ocular surface of patients with refractory dry eye disease (DED) because of Sjogren syndrome.
Methods: Twenty eyes of ten patients with severe immune-mediated DED were contralaterally randomized to receive either AS tears 50% or artificial tears between June 2021 and May 2023. Changes in tear stability, ocular surface staining, and in the morphology of the corneal sub-basal nerves were evaluated before treatment and at 1, 2, and 3 months after treatment using objective tests for DED and confocal microscopy.
