Stem Cell Biomarkers and their mechanisms in Prostate Cancer


Present there is little effective treatment available for castration resistant prostate cancer (PCa), which is the cause for most of prostate cancer related deaths. Emerging evidence suggested that cancer stem cells might play an important role in resistance to traditional cancer therapies, and the studies of cancer stem cells (including specific isolation and targeting on those cells) might benefit the discovery of novel treatment of prostate cancer, especially castration resistant disease.
Standard PCa treatment includes radical prostatectomy, radiotherapy, chemotherapy and castration (either by drug or by surgery, mainly for androgen sensitive PCa), as well as immunotherapy and palliative therapy (mainly for castration resistant PCa (CRPC)). CRPC is responsible for majority of the PCa-related deaths, and currently there are two major hypotheses of CRPC carcinogenesis, the adaptive mechanism and the selective mechanism. The adaptive mechanism suggests gene mutations in PCa cells (e.g., mutations of androgen receptor (AR)), dysregulated expression of genes, etc., contribute to CRPC development. The selective mechanism, which is emerged in the last few decades, suggests that pre-existing castration-resistant sub clones in primary PCa tissues and cancer stem cell selection dominates CRPC development. Recently, it has been suggested that stem-cell directed differentiation therapy could promote differentiation of cancer stem cells and sensitize them to anticancer drugs (such as synergistic androgen signalling blocking agents).

Cancer stem cells (CSCs) were defined as cells with capacity of self-renewal and proliferation in cancer tissue. Over years, scientists have been arguing about the origin of cancer stem cells. CSCs were suggested to originate from mutated normal stem cells, from mutated progenitor cells in the process of differentiation which re-gains the characteristics of stem cells, or from mature cells that re-acquired self-renewal ability.

Do Stem Cells act as Anti-Cancer Vaccines?

Induced Pluripotent Stem Cells iPSC are originated from skin or blood cells that have been reprogrammed back into an embryonic like pluripotent cells that enables the increase of an unlimited source of any type of human cell needed for therapeutic purposes. iPS cells plays an important role in regenerative medicine. They can become many different types of cells and tissues that can help in damage repair due to trauma or disease. Recent study shows that the iPS cells training the immune system to attack or even prevent tumours.  Ten years ago, adult cells were genetically reprogrammed to behave like pluripotent stem cells. To produce the vaccine for cancer, the researchers turned to induced pluripotent stem cells.  The main aim of the study is to vaccinate a person with his or her own iPS cells to protect against the development of many types of cancer. The iPS cells mimic Anti-Cancer vaccine because, since the cancer cells resemble immature progenitor cells, which ar

Cancer stem cells

How Cancer Persists Stem cells are found in numerous tissues in the body, its life span is limited unlike with all other regular cells. They have the ability of dividing and renovate themselves for long time period. There unspecialized character justifies that ensuring cells convert into different cell type on time when one cell divides. Like, stem cells inside the bone marrow have ability of becoming bone. Fat and blood cells Likewise, there is believed that cancer stem cell is present in the main part of tumour, in the other hand there growth is also undefined and ability of self-renovate till they convert into new cancer cells. The major tumours treatment leaves cancer stem cell unmarked. Cancer stem cell can move undetectably even after treatment of major tumours effectively to the blood stream by the immune system to generate new tumours. This process is known as metastasis. These minor tumours become more aggressive year after and it’s really difficult to treat them.

RESEARCH AND TRANSPLANT OF STEM CELL

Regenerative Medicine is used to Replace tissues and Organs which are been damaged by disease. It also helpful for the permanent damaged organs. This can be done through the cell based therapy or by using cell products. Most of the regenerative medicine is depend upon the endogenous developmental or repair process and stem cell plays a main role in regenerative medicine. And they are integral part of the Regenerative Medicine. The ability of stem cell is currently being researched by the doctors and scientists it can cure untreatable diseases like diabetes, heart failure stem cell also important in drug testing .These are used in Joints, Muscle pain, Ligaments. Regenerative Injection Treatment are using autologous platelet or plasma or bone marrow Tissue engineer is the branch of regenerative medicine. Cells are building block of tissues and Tissues are the main function in the body .Tissue engineering and Regenerative Medicine is the regeneration of cells and tissues and b
