Live cell therapy

I read in detail recently about a lady named Natalie Nichols, who now has a Christian ministry, who treated her very severe Lyme disease with live cell therapy. She doesn’t call it stem cell therapy, but says it is injections of shark cells. Her website is thorough in detailing her lyme journey (you can see video of her horrific neuro symptoms on YouTube as well). She says she began to get better with live cell therapy but I’ve never heard it mentioned here.... unless that’s the same as stem cells?

Just curious if anyone has heard of/tried this? I’ll link her page which details her lyme treatment

Shades of Grace is the ministry and I think there are links to video there and interviews she has done. I just think it’s interesting to see others stories of how the illness affects their lives and how so different treatment is for everyone.

Natalie says the doctors name is Velazquez in California, I think.
