Question

What is the difference between dedifferentiation and redifferentiation?

Answer 1

Dedifferentiation:

1. The cells that have lost their capability to divide and attain a specific function is known as differentiation.
2. When certain conditions are met, cells that have lost the ability to divide regain it.
3. Dedifferentiation is the process through which mature cells revert to their pluripotent state.
4. The cork cambium and inter-fascicular cambium are examples of dedifferentiated tissues.

Redifferentiation:

1. The cells divide and produce cells that once again lose their dividing capacity but mature to carry out particular tasks.
2. Redifferentiation is the event of losing the ability to divide by dedifferentiated cells.
3. Example: the secondary xylem and phloem formation in vascular cambium.

Dedifferentiation	Redifferentiation
The process by which a cell loses its ability to divide and attains a specific function is known as differentiation.	The phenomenon by which cells divide and produce cells that once again lose their dividing capacity but mature to perform specific functions.
2. It is manifested by a gene expression pattern, a change in the shape, protein expression pattern, and function.	2. It is both the process and the result of developing additional new characters.
3. Example: Interfascicular cambium and meristems-cork cambium formation from fully differentiated parenchymal cells	3. Example: Formation of secondary xylem and secondary phloem, secondary cortex cork from the interfascicular cambium, and cork cambium.
