Adenosine - a regulator of human testicular peritubular cells

ABSTRACT: Extracellular purines, particularly ATP and adenosine, are key regulators of physiological and pathophysiological processes throughout the human body. Despite their systemic importance, the specific roles of purinergic signaling in the human testis and their potential relevance for male fertility, are not well studied. As these processes cannot be readily studied in vivo, human testicular peritubular cells (HTPCs), which form the wall of seminiferous tubules, provide a unique and accessible in vitro model. HTPCs were isolated from testicular samples and cultured. Transcriptional profiles of adenosine-treated cells were analyzed using scRNA-seq, revealing strong upregulation of IL33, STAR, HIF1A, and others. Pathways linked to cell communication, migration and inflammation were enriched in HTPCs following adenosine treatment.

Effects of adenosine on human testicular peritubular cells

Project description:Extracellular purines, particularly adenosine and ATP, are supposed to regulate physiological and pathophysiological processes in the human testis. Cells that form the walls of the seminiferous tubules, known as human testicular peritubular cells (HTPCs), were isolated and treated with adenosine.

The molecular signature of human testicular peritubular cells revealed by single-cell analysis

Project description:Peritubular cells of the human testis form a small compartment surrounding the seminiferous tubules. It contrast to rodents, it is composed of several cell layers and extracellular matrix. Peritubular cells are crucial for sperm transport and emerge as contributors to the spermatogonial stem cell niche, yet testicular peritubular cells are among the least known cell types of the human body. We employed single-cell RNA sequencing of cultured human testicular peritubular cells (HTPCs) isolated from testicular samples of donors with normal spermatogenesis and compared our data with recently published ex vivo data and, if available, with immunohistochemical data of the Human Protein Atlas. We observed a significant overlap between our results and genes expressed in vivo. Based on expression of a set of smooth muscle markers, HTPCs can be classified as smooth muscle cells. Small differences between in vivo/in vitro expressed genes may be due to plasticity/phenotypic switching. Plasticity was also shown upon addition of FCS to the culture medium. Based on transcriptome similarities four cellular states were observed. Characteristics of mesenchymal stromal cells and Leydig stem cells were noted, yet differentiation attempts into fat cells, bone cells or mature Leydig cells were not successful. Further analyses confirmed known stem cell niche-relevant factors (e.g. GDNF) and identified unknown functions e.g. the ability to produce retinoic acid. The results reveal that HTPCs upon isolation and culture are a highly adequate cellular model as they retain major characteristics. They therefore allow us to define the signature and functions of human testicular peritubular cells. The data may serve as a resource for future studies to better understand male (in)fertility.

Proteomic insights into senescence of testicular peritubular cells from a nonhuman primate model

Project description:Age-related changes of the human testis may include morphological alterations, disturbed steroidogenesis and impaired spermatogenesis. However, the specific impact of cell age remains poorly understood and difficult to assess. Testicular peritubular cells fulfill essential functions, including sperm transport, contributions to the spermatogonial stem cell niche and paracrine interactions within the testis. To study their role in age-associated decline of testicular functions, we performed comprehensive proteome and secretome analyses of repeatedly passaged peritubular cells from Callithrix jacchus. This nonhuman primate model better reflects the human testicular biology than rodents and further gives access to young donors unavailable from humans. Among 5095 identified proteins, 583 were differentially abundant between samples with low and high passage numbers. The alterations indicate a reduced ability of senescent peritubular cells to contract and secrete proteins, as well as disturbances in NF-κB signaling and a reduced capacity to handle reactive oxygen species. Since this in vitro model may not exactly mirror all molecular aspects of in vivo aging, we investigated the proteomes and secretomes of testicular peritubular cells from young and old donors. Even though the age-related alterations at the protein level were less pronounced, we found evidence for impaired protein secretion, altered NF-κB signaling and reduced contractility of these in vivo aged peritubular cells.

RNA-Seq of testicular peritubular myoid cells, other testicular cells, and other tissue smooth muscle-like cells

Project description:In addition to germ cell population, testes contain several types of somatic cells, including Sertoli cells, Leydig cells, and peritubular myoid (PTM) cells. PTM cells are a type of smooth muscle-like cells and have contraction ability. To identify a marker of PTM cells, we isolated primary cells and subsequently performed RNA-Seq of testicular peritubular myoid cells (PTM_1, PTM_2, PTM_3), testicular Sertoli cells (Sertoli_1, Sertoli_2, Sertoli_3), testicular Leydig cells (Leydig_1, Leydig_2, Leydig_3), testicular germ cells (Germ_1, Germ_2, Germ_3), vascular smooth muscle cells (VSMC_1, VSMC_2, VSMC_3), intestinal smooth muscle cells (ISMC_1, ISMC_2, ISMC_3), and tracheal smooth muscle cells (TSMC_1, TSMC_2, TSMC_3) using BGISEQ-500 platform (BGI, China).
