These needs are met partially by the surrounding somatic cells and the cumulus-oocyte complex, which communicate bi-directionally via gap junctions. Identifying and analyzing protein expression in the oocyte can provide insight in its development and growth. Further, like bone marrow stem cells, if relevant marker genes are found in oocytes, there is a potential for the oocyte to be manipulated into becoming hemopoietic stem cells. In this study, porcine oocytes were isolated and subjected to microarray analysis to compare the oocyte gene expression in vivo and in vitro maturation (IVM). Genes identified belonged to both ‘hemopoietic or lymphoid organ development’(GO:0048534) and ‘immune system development’ (GO:0002520), and the markers can be used to identify several activities such as cell migration, neurogenesis and proliferation. The following are the identified genes and all were downregulated after IVM to varying degrees: ID2, VEGFA, TGFBR3, INHBA, CDK6, BCL11A, MYO1E, ITGB1, EGR1, NOTCH2, SPTA1, KIT and TPD52.

Cell-based assays are used to measure the level of proliferation and toxicity, as well as activation of signalling pathways and changes in morphology in cultivated cells. The studies conducted in vitro are aimed to estimate the newly synthesised drugs’ ability to permeate biological barriers and exert their therapeutic or cytotoxic effects. However, more than half of all studied drugs fail in the second or third phase of clinical trials due to a lack of confirmed efficacy. About a third of drugs fail because of safety issues, such as unacceptable levels of toxicity. To reduce attrition level in drug development, it is crucial to consider the implementation of translational phenotypic assays as well as to decipher various molecular mechanisms of action for new molecular entities.

These spherical units, secreted by most eukaryotic cells, attracted significant interest among researchers in recent years. Exosomes undergo secretion from almost all types of mammalian cells, including dendritic cells, B cells, epithelial cells, mastocytes, reticulocytes, platelets, T cells, mesenchymal stem cells, adipocytes, bone marrow-derived stem cells, embryonic stem cells, fibroblasts, cardiac myocytes, endothelial cells, oligodendrocytes, astrocytes, microglia, neurons, neural stem cells, hepatocytes, lung spheroid cells, as well as tumor cells. Exosomes have several features that enable many methods of their isolation from biological material. Furthermore, physicochemical properties such as size, mass, density, or the ability to interact with specific proteins allowed for the development and advance of several effective methods. Work on exosomes’ recovery and purity made it possible to most effectively determine their isolation methods’ efficiency and accuracy. A common ground for the researchers’ interest in exosomal analyses is the role of exosomes as carriers of disease biomarkers. It has been suggested that exosomes can be used in vaccine development and other immunological-related purposes, as one of their characteristics is the ability to present antigens. Moreover, exosomes have a long half-life. As the human body does not perceive them as foreign bodies, they can penetrate cell membranes and target specific cells, making them even better candidates for the applications mentioned above. Therefore, the following review deals with the nature of exosomes, as well as various methods of their isolation and use in medicine.

Although embryonic stem cells (ESCs) are capable of differentiation into all cell lineages, their utilization is associated with ethical concerns since they are obtained from embryos. Furthermore, ESCs may form teratomas or cause immune rejection in the clinical setting. Therefore, an effort has been made to utilize stem cells derived from adult tissues, especially mesenchymal stem cells (MSCs). A particularly attractive source of MSCs is the human umbilical cord, which is typically discarded after birth and considered a medical waste, therefore the acquisition of the cells is not associated with any health risk for a patient. Moreover, umbilical cord-derived MSCs do not express MHCII, thus they exhibit reduced immunogenicity. MSCs have been isolated from all compartments of umbilical cord, however the Wharton’s jelly-derived MSCs (WJ-M-SCs) are the most clinically utilizable. There are two techniques of UC-MSCs isolation: the enzymatic and explant procedures. The explant method involves cell outgrowth of tissue pieces placed into plastic culture vessel after mechanical splitting, whereas the enzymatic technique involves minced tissue digestion in an enzymatic solution.

They undergo highly dynamic changes during folliculogenesis and play a vital role in oocyte’s maturation. Recently, it has been shown that GCs also exhibit stem cell properties, since they express OCT-4, Nanog, Sox-2, which are markers of pluripotency, as well as several mesenchymal stem cell markers, such as CD29, CD44, CD90, CD105, CD117 or CD166. In addition, GCs are able to differentiate towards neurogenic, chondrogenic and osteogenic lineages. Since the use of embryonic stem cells in regenerative medicine is burdened with ethical concerns and the risk of immune rejection or teratoma formation, adult stem cells are emerging as a promising alternative. GCs especially seem to provide a promising source of stem cells, since they are easily obtainable during assisted reproduction techniques. In order to better understand the genetic changes taking place in proliferating granulosa cells cultured in vitro, we isolated GCs from 40 prepubertal gilts and cultured them in vitro for 168 h. After 24, 48, 72, 96, 120, 144 and 168 h of cultivation the total RNA was extracted, reverse transcription was conducted and RT-qPCR reaction was performed.

The proper development of oocytes requires close communication with surrounding somatic cells, the substances they emit allow proper maturation of oocytes. Somatic cumulus (CC) cells and oocytes form cumulus-oocyte (COC) complexes. In this study, the Affymetrix microarray analysis was used to investigate changes in gene expression occurring in oocytes before and after in vitro maturation (IVM). The aim of the study was to examine oocyte genes involved in two ontological groups, “regulation of cell migration” and “regulation of cell proliferation” discovered by the microarray method. We found a reduced expression of all 28 genes tested in the ontological groups: ID2, VEGFA, BTG2, CCND2, EDNRA, TGFBR3, GJA, LAMA2, RTN4, CDK6, IHH, MAGED1, INSR, CD9, PTGES, TXNIP, ITGB1, SMAD4, MAP3K1, NOTCH2 , IGFBP7, KLF10, KIT, TPM1, PLD1, BTG3, CD47 and MITF. We chose the most regulated genes down the IVM culture, and pointed out those belonging to two ontological groups. Increased expression of the described genes before IVM maturation may indicate the important role of these genes in the process of ovum maturation. After the maturation process, the proteins produced by them did not play such an important role. In summary, the study provides us with many genes that can serve as molecular markers of oocyte processes associated with in vitro maturation.

The oviductal epithelium is characterized by the presence of ciliary cells, supporting the movement of cumulus-oocyte complexes towards the uterus. By interacting with the semen, the epithelium of the fallopian tube makes the sperm acquire the ability to fertilize. So far, the exact molecular mechanisms of these changes have not been known. Hence, understanding the metabolism of oviduct epithelial cells and the level of expression of individual groups of genes seems to be a way to deepen the knowledge about the broadly understood reproduction. In our research, we decided to culture oviductal epithelial cells (OECs) in vitro for a long period of time. After 24h, 7, 15 and 30 days, the OECs were harvested, with their RNA isolated. Transcriptomic changes were analyzed using microarrays. The “cellular response to lipid” group was represented by the following genes: MUC1, CYP24A1, KLF4, IL24, SNAI2, CXCL10, PPARD, TNC, ABCA10, while the genes belonging to the “cellular lipid metabolic processes” were: LIPG, ARSK, ACADL, FADS3, P2RX7, ACSS2, PPARD, KITLG, SPTLC3, ERBB3, KLF4, CRABP2. Additionally, PPARD and ACADL were members of the “fatty acid beta-oxidation” ontology group. Our study describes genes that are not directly related to fertility processes. However, significant changes in their expression in in vitro cultured OECs may indicate their usefulness as markers of OECs’ physiological processes.
