What is Differentiation? |
Differentiation is the process by which unspecialised cells become specialised. |
|
|
List examples of specialised cells and tissues... |
Cells: 1. Epithelial Cell 2. Nerve Cell 3. Red Blood Cell 4. Goblet Cell Tissues: 1. Connective Tissue 2. Muscle Tissue 3. Nervous Tissue |
|
|
Define the term 'Stem Cell'... |
Stem Cells are unspecialised Cells that can divide to self-renew and/or differentiate into specialised cells. |
|
|
The two types of stem cells are... |
1. Embryonic 2. Adult |
|
|
Pluripotent / Multipotent ? |
Pluripotent: -Found in Embryonic Stem Cells -Can develop into 200+ cells Multipotent: -Found in Adult Stem Cells -They have the ability to develop into only a few distinct types -Are involved in the growth, repair and renewal of their surrounding cells |
|
|
What is a somatic cell? |
- Somatic Cells are differentiated cells that form the different types of tissue that exist. - They divide by MITOSIS -They produce HAPLOID CELLS |
|
|
What are germline cells? |
- A germline cell is a cell that will become a gamete or the cells that produce gametes -They can divide by MEIOSIS to produce identical daughter HAPLOID CELLS -They can divide by MITOSIS to produce DIPLOID CELLS |
|
|
Therapeutic applications of stem cells... |
1. Skin Grafts 2. Corneal Grafts 3. Bone Marrow transplant |
|
|
CANCER CELLS |
-Cancer cells divide uncontrollably to produce a mass of abnormal cells. -Cancer cells do not respond to regulatory signals. -A secondary tumour is caused if they fail to attach to each other. |
