16 Citations | Taken together, we can use selective processes to generate more effective stem cells to treat cancers as is clearly needed today. |
In order to obtain more stem cells, we can subculture ADSCs every 14 days instead of the normal 5 days. | |
The use of stem cells from young donors or the rejuvenation of aged patient-derived stem cells may represent part of a solution. | |
298 Citations | Stem cells can be used in cellular therapy to replace damaged cells or to regenerate organs. |
16 Citations | Once these questions have been addressed, the use of stem cells in clinical practice can be realized. |
Open access•Journal Article 19 Citations | For their unique properties stem cells promise to be of universal use in clinical medicine, especially in regeneration of many organs and tissues in the human body. |
Substantial quantities of stem cells of an excellent quality and at early (2–5) passages are necessary for clinical use, which currently is a problem for use of adult stem cells. | |
Fischbach added that unlike pluripotent stem cells, adult stem cells may be only capable of dividing a limited number of times, which would limit their therapeutic usefulness. | |
Open access•Journal Article 34 Citations | Unlike muscle cells, blood cells, or nerve cells -- which do not normally replicate themselves - stem cells may replicate many times. |
165 Citations | We propose that many cancer cell lines contain a minor subpopulation of stem cells that is enriched in a SP, can be maintained indefinitely in culture, and is crucial for their malignancy. |
Nevertheless, in addition to the achievements in stem cell research, many challenges still need to be overcome for stem cells to have versatile application in clinics. | |
Therefore, the use of adult stem cells, which are multipotent or unipotent, can be at present a more achievable strategy. |

How to use stem cell for cancer therapy?5 answersStem cells have emerged as a promising tool in cancer therapy due to their unique abilities. Cancer stem cells (CSCs) are crucial for tumor initiation, progression, and metastasis, making them a target for therapy. Studies focus on various stem cell types like mesenchymal stem cells (MSCs) and induced pluripotent stem cells (iPSCs) for their tumor-homing properties and anti-cancer effects. The "stemness" properties of CSCs, including self-renewal and differentiation capacity, contribute to therapy resistance and cancer relapse, highlighting the importance of targeting CSCs in treatment. Stem cells can be utilized to deliver drugs to tumor sites, enhance survival rates, and reduce tumor volume, showing promise in pre-clinical trials. Overall, utilizing stem cells in cancer therapy involves leveraging their unique characteristics to target and treat cancer effectively.
What ethical issues are associated with the use of stem cells?4 answersThe ethical issues associated with the use of stem cells include concerns about the source of human embryonic stem cells and the derivation and use of other stem cells that have the capacity to differentiate into all types of human tissue. There are also ethical considerations regarding the use of induced pluripotent stem cells (iPSCs), which have the potential to avoid the destruction of human embryos. Additionally, there are ethical challenges related to the use of stem cells in clinical research and the translation of basic stem cell knowledge into safe and effective patient therapies. The procurement and use of pluripotent stem cells, including human embryonic stem cells and induced pluripotent stem cells, also raise ethical considerations. These ethical issues need to be addressed in order to ensure the responsible and ethical use of stem cells in research and clinical applications.
What are the practical uses of stem cells?5 answersStem cells have practical uses in various medical fields, including cellular therapy, regenerative medicine, and the treatment of neurological diseases. They can be used to replace damaged cells and tissues, aiding in the regeneration and repair of organs. Stem cell therapy shows potential in treating diseases such as leukemia, lymphoma, neuroblastoma, multiple myeloma, spinal cord injuries, diabetes, Parkinson's disease, Alzheimer's disease, heart disease, stroke, burns, cancer, and osteoarthritis. Additionally, stem cells have the ability to stop immune responses, making them useful in diseases where organs are damaged or the immune system is overactive. Pluripotent stem cells, in particular, have the potential to differentiate into all adult cell types, making them valuable in disease modeling and regenerative medicine. Genome editing tools like CRISPR Cas9 can be used to manipulate stem cells for studying and treating human diseases.
