Abstract

Stem cell research and therapy are progressing these days dramatically. Stem cell therapy holds enormous treatment potential for many diseases which currently have no or limited therapeutic options. Unfortunately, this potential also comes with side-effects. In this review, the positive and negative effects of regulation of stem cells will be explained. Stem cells are undifferentiated cells which able to develop into many different cells of types in the body during early life and growth. There are five types of stem cells: embryonic stem cells, induced pluripotent stem cells, somatic stem cells, fetal stem cells and mesenchymal stem cells. Stem cell transplantation is one form of stem cell therapy, it comes with different techniques sourced, and those are autologous and allogeneic transplantation stem cells. In an autologous transplant, a patients blood-forming stem cells are collected, meanwhile, in an allogeneic transplant, target cells are replaced with new stem cells obtained from a donor or donated umbilical cord blood. Its abilities to maintain the phenotype, self-renewing and differentiate itself into specialized cells, give rise to stem cell as an innovation for the treatment of various diseases. In the clinical setting, stem cells are being explored for different conditions, such as in tissue repair and regeneration and autoimmune diseases therapy. But along with its benefit, stem cell therapy also holds some harm. It is known that the treatment using stem cell for curing and rehabilitation has the risk of tumor formation.Keywords: stem cell, therapy, transplantation, tumorigenic, mesenchymal stem cell, allogeneic

Abstract

Dendritic cell (DC) vaccines, as immunotherapy agents, can gather up and transport cancer-related antigens to T lymphocytes, activating anti-tumor effector responses. After being activated by DC, cytotoxic T lymphocyte cells (CTL) will secrete the cytolytic granzyme B that can effectively induce rapid apoptosis of target cells. On the other hand, DC also secrete several cytokines and a large number of exosomes, which together operate as a whole antigen-presenting entity. The efficacy of the vaccine’s treatment may be affected by the sources used for DC vaccines. Umbilical cord blood (UCB) from healthy donors can be employed when autologous cancer patient’s peripheral blood (PB) cannot be used as a source for isolating DC due to genetic abnormalities. Comparing UCB to other sources, there is a painless method of collecting sources as opposed to PB, which necessitates a venipuncture or leukapheresis procedure to isolate the blood. Many studies related to the use of PB-DC have been carried out, but research on potential comparisons between PB-DC and UCB-DC is still very limited. In this review, the potential of PB- and UCB-derived DC and their secretomes for cancer will be discussed.Keywords: dendritic cells, vaccines, umbilical cord blood, peripheral blood
