Embryonic Stem Cells Ethical Pros And Cons – The debate over stem cell research arises from accusations that the use of embryos for research purposes is unethical. In the process of carrying out research activities, the embryo was destroyed. Protesters of this kind of research oppose the killing of embryos, calling this activity murder.

This research can be useful in finding cures for health problems such as Parkinson’s disease, diabetes, stroke, Alzheimer’s disease, organ transplants, spinal cord injuries, birth defects, etc. Embryonic cells have the ability to reproduce other cells in the body. The debate over the use of these cells for research has been fierce between religious groups and scientists. According to the first group, the use of embryos is considered immoral because it can destroy life at an early stage of development.

Stem Cells Across Curriculum

Embryonic stem cells offer great flexibility but have ethical limitations and challenges such as tumor formation. Although adult stem cells alleviate ethical concerns, they lack the flexibility afforded by embryonic stem cells. To harness the full potential and overcome the current limitations of embryonic and adult stem cells, further research is essential as discussed in this study.

Embryonic stem cells (ESC) are a type of pluripotent stem cell that originate from the inner cell mass of the blastocyst, an early stage pre-implantation embryo that is approximately 5-6 days old. These cells are characterized by their ability to differentiate into all cell types of the three germ layers: endoderm, mesoderm, and ectoderm. Additionally, ESCs can self-renew, meaning they can reproduce and maintain an undifferentiated state indefinitely under the right conditions.

There are basically two types of pluripotent stem cells: pluripotent stem cells (ESCs) and induced pluripotent stem cells (iPSCs). As discussed previously, ESCs originate from the inner cell mass of the early embryo. In contrast, iPSCs are reprogrammed somatic cells, in which factors such as Oct4, Sox2, Klf4, and c-Myc induce a pluripotent state similar to that of ESCs.

Embryonic Stem Cells Ethical Pros And Cons

Despite their similarities, pluripotent and totipotent cells have significant differences. Although pluripotent stem cells can differentiate into any cell type of the three germ layers, they cannot form a complete organism. On the other hand, totipotent cells, such as zygotes and early cleavage stage embryo cells, can differentiate into all embryonic and extraembryonic tissues, which means they have the potential to form complete organisms, including the placenta.

Origins, Ethics And Embryos: The Sources Of Human Embryonic Stem Cells

Embryonic stem cells play an important role in human development, especially during gastrulation – the process by which a simple, single-layered blastula is reorganized into a multi-layered structure called a gastrula. Cells from the inner cell mass, which are embryonic stem cells, give rise to the three germ layers – endoderm, mesoderm, and ectoderm – which ultimately differentiate into all the tissues and organ systems in the body.

Cell markers, proteins expressed on the surface of cells or inside cells, are critical for identifying and isolating embryonic stem cells. These include alkaline phosphatase, stage-specific embryonic antigen-4 (SSEA4), tumor rejection antigen (Tra-1-60, Tra-1-81), and transcription factors such as Oct4, Nanog, and Sox2. Identification of these markers can help maintain culture purity or monitor cell differentiation.

Cell culture is an important process in regenerative medicine, allowing scientists to grow and manipulate cells under controlled laboratory conditions. This allows the study of cell behavior, including proliferation, differentiation, and response to various stimuli. It also enables large-scale production of cells for therapy and development of disease models to study pathogenesis and test potential treatments.

For ESC culture, feeder cells and specific culture media are essential to maintain the undifferentiated state of the cells. Feeder cells, usually mouse embryonic fibroblasts, provide the necessary growth factors and prevent cell differentiation. Meanwhile, the culture medium supplies ESCs with necessary nutrients, and may also contain additional growth factors such as leukemia inhibitory factor (LIF) and basic fibroblast growth factor (bFGF), which help maintain pluripotency.

Embryonic Stem Cell Research Pros And Cons

By manipulating the types and concentrations of growth factors and transcription factors in the culture environment, scientists can guide cells that differentiate into specific cell types. Some factors encourage the maintenance of pluripotent states, while others encourage differentiation towards particular lineages. This controlled differentiation is critical for generating specific cell types for cell-based therapies or disease models.

Cell signaling pathways play an important role in the maintenance and differentiation of ESCs. Signals from surrounding cells or components of the culture medium can influence the ESC cell cycle, either promoting self-renewal, proliferation, or triggering differentiation. In addition, the ESC cell cycle must also be precisely controlled, with disruption potentially leading to differentiation or apoptosis.

Reprogramming refers to the process of converting differentiated cells to a pluripotent state, creating so-called induced pluripotent stem cells (iPSCs). This is usually achieved by introducing transcription factors such as Oct4, Sox2, Klf4, and c-Myc, which return the cells to a state similar to that of ESCs. This offers a potential source of pluripotent cells for research and therapy without the ethical issues associated with ESCs.

Embryonic Stem Cells Ethical Pros And Cons

Embryonic stem cells can be used in tissue engineering to create complex tissue structures, or organoids, through controlled manipulation of pluripotency and differentiation. Organoids can model disease in a more differentiated manner than 2D cultures by recapitulating some aspects of organ complexity.

Stem Cell Therapy

Embryonic stem cells provide a powerful platform for disease modeling and drug screening due to their capacity for unlimited self-renewal and potential to differentiate into any cell type. Researchers can generate cells that represent specific diseases, then use these cells to test potential drugs, including assessing drug efficacy and side effects.

Embryonic stem cells have great therapeutic potential in regenerative medicine, especially for conditions where existing cells are lost or damaged. Scientists can differentiate ESCs into specific cell types, then transplant those cells into patients to replace diseased or damaged cells. Potential applications range from diabetes, Parkinson’s disease, spinal cord injury, to heart disease.

Although ESCs and iPSCs have the same pluripotency, their origins are different. ESCs originate from early-stage embryos, while iPSCs are reprogrammed from adult somatic cells. Furthermore, because iPSCs are usually produced from the patient’s own
