Stem Cells & Immunity?

Hello,

I am trying to better understand about stem cells activities related
to immune status. I read about following issue:-

"4. Cortisone (steroid) or non-steroidal anti-inflammatories do not
belong anywhere in the treatment process. Their use will inhibit
engraftment and mask any adverse events. This will lead to a failed
response to the treatment. Stem cells rely on inflammation to guide
their homing and this is switched off by any anti-inflammatory -
resulting in no treatment response.

5. Multiple invasive procedures confer no extra benefit, and lead to
higher risk of contamination, infection and results in greater trauma
and therefore less response to therapy. The reason for the lesser
response is that trauma is inflammation and attracts stem cells, which
are wasted on the damage caused, and not on the disease the patient
wanted treatment for in the first place. In addition, repeated lumbar
punctures can lead to long-term back pain.

"

Is it true that medical interventions by anti-inflammatory durgs &
steriods can interfere in normal defence activities by stem cells?

Will you tell me more about stem cells relevance with status of immune
defence response? Can stem cells normal activities be compromised or
weakened causing weak defence responses & abnormal healing?

Best wishes.

I can't say if anti-oxidants can also act as antiinflammatorys in this
regard.
It can be important to understand that if immuno-compromise,
immunodefficiency, scar formations, delayed & abnormal healings are
related stem cells decreased activities. So it can be interesting to
understand stem cells weakness & immobilization.

Yes.  There are probably a host of different interventions that could 
interfere with the complement cascade.  Vitamin D and growth hormone are 
two other factors with which you should not interfere.

Are you asking what repeated harvesting from bone marrow will do or are 
you asking about stem cell procedures that restore immunity?

Sometimes in colitis, the body develops an antibody against an important 
component in macrophage function (IL-10 or GM-CSF).  The result can be 
chronic inflammation in the gut which can be healed with PRP - 
platelet-rich prolotherapy - which essentially draws stem cells to the 
site of a wound more effectively.  It's also the case that certain stem 
cell treatments can lead to a suppression of autoimmunity which, for 
instance, could resolve macrophage dysfunction in a case of colitis.

My modeling indicates it can.  For instance, cathelicidin is important 
in both preventing infection and mobilizing stem cells.  Anything that 
interferes with it - like TNF-alpha or high iron consumption - probably 
would damage some repair component like angiogenesis while inhibiting 
immune response (like through TLR2).
