Vince asks: I am geting my bone marrow stem  cell injection for my kidney disease, tuesday,jan. 12, at dr. steenblocks clinic in orange county, Ca.
Will the stem cells get trapped in my lungsand is it dangerous?
Could you please let me know before i leave?

The ICMS responds: First, adult stem cells injected IV end up in the lungs, not the kidney. See this LINK
If you want them in the kidney, they need to be placed there. The issue of growing stem cells has been addressed by the ICMS.  The clinical guidelines HERE discuss that culturing up to a month is likely safe.  However, that's only one small question to ask. 

ICMS offers certification for practitioners and labs, so the first question is, are you ICMS certified?  If not, then here's a list of questions to be asked:

How is the bone marrow collected?  In our experience, without the use of x-ray guidance, you're as likely to pull blood versus bone marrow.
Blood doesn't contain the type of stem cells you would want, so performing a bone marrow aspiration without imaging to make sure you're
in the marrow space, is like flipping a coin for a stem cell harvest.

What third party accredits your lab?  There should be an outside agency that holds the lab to strict third party guidelines, a record of lab
inspections, etc...  Third party organizations would include private parties like Reglera.

Specifically, how are the cells grown?  What is the culture media?  If the culture media is fetal calf serum or fetal bovine serum, what steps
have been taken to make sure there is no contamination from Bovine Spongiform Encephalopathy?

Are the cells being grown periodically tested using flow cytometry to determine what's being grown?  This technology identifies the type of
cells being grown using surface markers.

What are the stem cell types being grown?  Hematopoetic Stem Cells vs. Mesenchymal Stem Cells, other?

Are the cell cytogenetically tested and if so, what is the cell release criteria?  This test is an additional safety check for the cells.

What type of complications tracking system is being used?  Do they contact patients and adjudicate complaints?  This means that they go out
and contact patients about possible complications and that each compliant registered by a patient (even I got a cold after your
procedure) is adjudicated by someone using HHS criteria, i.e. Unlikely to be related to the procedure, possibly related, unlikely to be
related, etc...  ICMS has strict guidelines about how this should be done.
