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. http://www.regenecell.com/article-guidelines-for-stem-cell-therapy.htm " 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.

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.

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