Title

ROLE OF SOMATIC TESTICULAR CELLS DURING MOUSE SPERMATOGENESIS IN THREE-DIMENSIONAL COLLAGEN GEL CULTURE SYSTEM

Pages

  79-90

Abstract

 Objective: SPERMATOGONIAl stem cells (SSCs) are the only cell type that can restore fertility to an infertile recipient following transplantation. Much effort has been made to develop a protocol for differentiating isolated SSCs in vitro. Recently, three-dimensional (3D) culture system has been introduced as an appropriate microenvironment for clonal expansion and differentiation of SSCs. This system provides structural support and multiple options for several manipulation such as addition of different cells. Somatic cells have a critical role in stimulating SPERMATOGENESIS. They provide complex cell to cell interaction, transport proteins and produce enzymes and regulatory factors. This study aimed to optimize the culture condition by adding somatic testicular cells to the collagen gel culture system in order to induce SPERMATOGENESIS progression.Materials and Methods: In this experimental study, the disassociation of SSCs was performed by using a two-step enzymatic digestion of type I collagenase, hyaluronidase and DNase. Somatic testicular cells including Sertoli cells and peritubular cells were obtained after the second digestion. SSCs were isolated by Magnetic Activated Cell Sorting (MACS) using GDNF family receptor alpha-1 (Gfra-1) antibody. Two experimental designs were investigated.1. Gfra-1 positive SSCs were cultured in a collagen solution.2. Somatic testicular cells were added to the Gfra-1 positive SSCs in a collagen solution. SPERMATOGENESIS progression was determined after three weeks by staining of synaptonemal complex protein 3 (SCP3) -positive cells. Semi-quantitative Reverse Transcription PCR was undertaken for SCP3 as a meiotic marker and, Crem and Thyroid transcription factor-1 (TTF1) as post meiotic markers. For statistical analysis student t test was performed.Results: Testicular supporter cells increased the expression of meiotic and post meiotic markers and had a positive effect on extensive colony formation.Conclusion: Collagen gel culture system supported by somatic testicular cells provides a microenvironment that mimics seminiferous epithelium and induces SPERMATOGENESIS in vitro.
