The umbilical cord of a healthy neonate contains within it a multipotential treatment for a myriad of diseases and injuries. What was once tossed into the biohazard waste without a second thought is now known to be a goldmine of antigenically immature cells that rival the use of bone marrow for reconstitution of blood lineages. Umbilical cord blood (UCB) is emerging as an effective and feasible clinical treatment as its availability increases and benefits are realized. Basic science research has demonstrated a broad therapeutic capacity ranging from cell replacement to cell protection and anti-inflammation in a number of animal disease and injury models. UCB is easily obtained with no harm to infant or mother and can be stored at cryogenic temperatures with relatively little loss of cells upon thaw. The heterogeneous mononuclear fraction has been identified and characterized and transplanted both locally and systemically to treat animal models of stroke, myocardial infarction, Amytrophic Lateral Sclerosis, San Filippo, spinal cord injury, traumatic brain injury, and age-related neurodegeneration, among others. In the pages to follow, we share protocols for the identification and research use of the mononuclear cell fraction of UCB.

Premature deliveries and preterm newborns are of a special significance to obstetricians. Despite great improvement in neonatal intensive care in the last two decades, prematurity is still the leading cause of neonatal mortality and morbidity. Complications associated with premature deliveries are malpresentation, prolapse of the umbilical cord, entrapment of some parts of the fetal body, as well as severe bruising or bone fractures.

Melanoma is among the most common malignancies and has recently exhibited increased resistance to treatments, resulting in a more aggressive disease course. Mesenchymal stem cells (MSCs) secrete cytokines both in vivo and in vitro, which regulate tumor cell signaling pathways and the tumor microenvironment, thereby influencing tumor progression. This study investigates the anti-melanogenesis effects of sheep umbilical cord mesenchymal stem cells (SUCMSCs) to assess their potential application in melanoma treatment.

Placentation disorders, including severe preeclampsia and fetal growth restriction, have their origins in early pregnancy, whereas symptoms typically present later on. To investigate the pathogenesis of these diseases, there is a need for a reliable in vitro model system of early placenta development with known pregnancy outcomes. Therefore, we optimized the generation of human induced trophoblast stem cells (iTSCs) from term umbilical cord, enabling non-invasive collection of patient-derived material immediately after birth.

Retinal diseases are characterized by progressive damage to retinal cells, leading to irreversible vision loss. Among these, glaucoma stands out as a multifactorial neurodegenerative disease involving elevated intraocular pressure, retinal ganglion cell apoptosis, and optic nerve damage, ultimately resulting in blindness in both humans and dogs. Stem cell-based therapies have emerged as a promising therapeutic option for such conditions due to their regenerative and neuroprotective potential.

The global issue of aging populations has become increasingly prominent, thus the research and development for anti-aging therapies to assure longevity as well as to ameliorate age-related complications is put high on the agenda. The young humoral milieu has been substantiated to impart youthful characteristics to aged cells or organs. Extracellular vesicles (EVs) are a heterogeneous group of cell-derived membrane-limited structures that serve as couriers of proteins and genetic material to regulate intercellular communication.
