    Objective: Mesenchymal stem cells are used in various fields, such as cellular therapy, regeneration, or tissue engineering. It has been shown that they exhibit many protective factors and also work as a modulating chief within the region in which they are administered. There are studies on both the therapeutic and neuroprotective effects of brain-derived neurotrophic factor. Also, there are many studies on the improvement of culture conditions for in vitro reproduction of mesenchymal stem cells, which can be obtained from many sources in various bodies, such as adipose tissue and Wharton's jelly. Improving and standardizing these culture conditions will increase the effectiveness and reliability of stem cell therapies. Studies evaluating many culture conditions, such as O-2 level, type of medium, monolayer culture, and the transition from in vitro 3D models, are ongoing. Materials and Methods: In our study, groups were formed by using stem cells originating from adipose tissue and Wharton's jelly. Stem cell cultures were made using Hillex-II and Pronectin-F microcarriers. Cell culture O-2 level was adjusted as 1% and 5% for each group separately. Enzyme-linked immunosorbent assay was used to analyze brain-derived neurotrophic factor levels in stem cell culture fluid. Results: The highest brain-derived neurotrophic factor level in mesenchymal stem cells culture medium was observed in an adipose-derived stem cell culture with an in vitro fertilization (non-treated) dish, using a Hillex microcarrier in a 1% O 2 microenvironment. Conclusion: As a result of our observations, we think that cells could exhibit greater therapeutic potential in a dynamic adhesion environment.

    The effect of anesthetic agents used in oocyte collection on intracytoplasmic sperm injection results in patients treated for infertility due to male factor

    Aim: Different anesthetic methods and agents are used for transvaginal oocyte retrieval procedures (TORP) in assisted reproductive techniques (ART). In our study, we evaluated prospectively the effect of propofol and thiopental sodium during TORP on intracytoplasmic sperm injection (ICSI) results in the spouses of patients with male factor indication.Material and Methods: The study was approved by the ethics committee with Protocol No. 2019-21-07 on dated October 28, 2019. Sixty female patients who underwent TORP for intracytoplasmic sperm injection were included in the study. Anesthesia was randomized into two groups according to propofol (GP) or thiopental sodium (GT) used for induction and maintenance anesthesia. Patients' demographic data, effects of the anesthetic drug used on hemodynamics and nausea and vomiting, laboratory parameters including fertilization rate, cleavage rate, optimal embryo rate and implantation rate, and pregnancy outcomes were recorded.Results: Sixty patients, including the propofol group (n:30) and the thiopental sodium group (n:30), were evaluated. Mean age, body mass index and motile sperm count were similar in both groups. Mean arterial pressures and nausea and vomiting rates were lower in GP (p<0.05). Although intracytoplasmic sperm injection, pronucleus, MII oocyte values were statistically significantly higher in GP, B-HCG and clinical pregnancy outcomes were similar in both groups.Discussion: Our findings revealed that propofol and thiopental sodium, the anesthetic agents used in transvaginal oocyte collection procedure before ICSI treatment, had similar effects on clinical pregnancy. The results of our study are similar to many studies in the literature.
