answer -

GENE THERAPY

STEM CELL THERAPY

1. It involve the transfer of the gene by a vector to the target individual cell

2. it involve the transfer of the gene via the carrier , it can be viral vector and nonviral vector.

1. it invove the transfer of the stem cell into the patient .

2. stem cell therapy involve the risk like the loss of control on the cell division

example that have been achieved using gene therapies is -

- The treatment of the haemophilia A and B due to the defect in the clotting factor gene can be corrected by the gene tranfer therapy .

- CFTR gene transfer to treat cystic fibrosis

answer - difference bw embryonic stem cell and adult stem

Embryonic stem cell(ESC)

adult stem cell (ASC)

1. it is found in the germline

2. ESC based therapy are less advantageous and safe

3. ESC are pluripotent

4 undergo late apoptosis

1. it is found in the differentiated tissue

2. ASC based therapy more safe and advantageous

3. ASC are multipotent

4. undergo

advantages of the ESC -

these cells are undifferentiated hence can be used in all part of the body as a stem cell therapy.

disadvantages

due to lack of the knowledge about these embryonic stem cells , using them can create problem.

sometime they start dividing uncontrollably.

advantages of the adult stem cell -

these cell can be transformed into the puripotent stem cell.

these stem cells are not rejected by the self .

Disadvantage

they are difficult to culture to invitro.

making these cells induced pluripotent stem cells from the adult stem cell is difficult
