Foreign cells can they survive and divide using its own dna

In summary: Yes, sometimes it is possible for two cells that are both of the same type (for example, a kidney and a nerve cell) to be successfully transplanted into a new host body, but only the DNA structure of the two cells will differ. It is possible for a person to receive transplanted organs from a close relative (a twin, for example) but this is not always successful. A person's immune system can sometimes reject cells from a close relative even if the cells are of the same type. Stem cells are being used to generate an organ using foreign stem cells, but this process is not always successful. If the foreign cells are being used to grow an entire organ, then the new cells will differ only by their DNA

If a foreign human cell is introduced into one's body by way of blood transfusion or through some other method could these foreign cells survive and take up host in their new environment ? So if a foreign nerve cell is introduced could this nerve cell take up host as a native cell where it can function normally ? Also would this foreign nerve cell eventually divide and copy its own DNA or will it be able to divide and copy the DNA of their new host (body) ?

Yes sometimes it is possible for somebody involved in a medical emergency to be helped by blood transfusion and skin grafts, kidneys and other transplants too.
The donor has to be a close as possible genetically to the recipient, (ideally a twin).
It can happen with transplanted organs that the recipient's immune system still rejects cells even from a quite close relative.
Blood transfusions generally are OK, they keep the patient alive while their body recovers from trauma and generates it's own new blood cells.
It doesn't matter that the transfusion blood cells eventually die, the patient lives.

Hello and thank you for the response. Can you tell me if two cells are both completely identical as to its type (say kidney or nerve) but only the DNA structure differs could this cell survive in a host (recipient) body ? May I ask what can be said about stem cells ? Stem cells are being used to generate an organ using foreign stem cells no ? If these foreign cells are being used to grow an entire organ then would these new cells differing only by DNA not survive ?
 

1. Can foreign cells survive and divide using their own DNA?

Yes, foreign cells can survive and divide using their own DNA. This process is known as autonomous cell division, where the foreign cells are able to replicate and divide independently from the host organism.

2. How do foreign cells obtain their own DNA?

Foreign cells can obtain their own DNA through a process called horizontal gene transfer. This can occur through mechanisms such as conjugation, transformation, and transduction.

3. Can foreign cells survive in a foreign environment?

Yes, foreign cells can survive in a foreign environment as long as they have the necessary resources and conditions to sustain themselves. This may include nutrients, suitable temperature, and protection from harmful elements.

4. Can foreign cells integrate with the host organism's DNA?

Yes, foreign cells have the ability to integrate with the host organism's DNA through a process called genetic recombination. This can lead to the exchange of genetic material between the foreign cells and the host organism.

5. Is the survival of foreign cells beneficial or harmful to the host organism?

The survival of foreign cells can have both beneficial and harmful effects on the host organism. On one hand, it can introduce new genetic traits and diversity, but on the other hand, it can also lead to the spread of infectious diseases or cause disruptions in the host's normal cellular functions.
