Study Notes
Stem Cells
- Stem cells are undifferentiated cells that can become many types of cells
- Differentiation refers to an unspecialized cell taking on the characteristics of a specialized cell, such as heart, liver, or muscle cells.
- Embryonic stem cells are extracted from embryos 3-5 days after fertilization.
Cell-Based Therapies
- Cell-based therapies use stem cells to repair or replace damaged cells or tissues.
- Stem cell therapies have many potential benefits, such as treatment for diabetes, heart disease, and skin grafts.
- Cell-based therapies could reduce the need for organ transplants and donors.
Ethical Considerations
- Using embryonic stem cells is controversial as it involves destroying embryos, raising concerns about the value of life.
- Donor consent is a significant ethical issue.
Privacy Concerns
- Stem cell research involves storing genetic information, which could be misused or leaked, compromising privacy and potentially leading to discrimination.
Access Equity
- Stem cell treatments are costly and not equally accessible to everyone, with disparities in access between different regions.
Procedure Risks
- Some stem cell procedures are invasive and involve discomfort with potential long-term effects that are not fully understood.
Freedom of Choice Issues
- There may be pressure to donate stem cells, and patients may not fully understand the risks and benefits due to the complex nature of the treatments.
Stem Cells
- Stem cells are unspecialised cells that can differentiate into various cell types.
- Differentiation is the process by which an unspecialised cell develops into a specialised one, such as heart, liver, or muscle cells.
- Embryonic stem cells are extracted from human embryos between 3-5 days after fertilisation.
Stem Cell Therapies
- Cell-based therapies involve inducing stem cells to differentiate into specific cell types to repair damaged or destroyed cells and tissues.
- These therapies hold potential for treating diseases like diabetes and heart disease, as well as for skin grafts and potentially reducing the need for organ transplants.
Ethical Considerations
- Using embryonic stem cells is controversial, as it involves the destruction of embryos, raising concerns about the value of life.
- Obtaining consent from donors can pose ethical challenges.
Privacy Concerns
- Stem cell research involves storing genetic information, which can lead to privacy risks and potential misuse or leakage, potentially resulting in discrimination.
Equity of Access
- Stem cell treatments are expensive and not readily available to everyone, leading to unequal access for people in different regions.
Invasiveness and Potential Risks
- Some stem cell procedures are invasive, risky, and may cause discomfort.
- The long-term effects of stem cell therapies are not yet fully understood.
Freedom of Choice
- There may be pressure to donate stem cells.
- The complexity of stem cell treatments can make it challenging for patients to fully understand the risks and benefits.
