Thanks Andy. I checked with Eileen and she mentioned that either company is good. but they have used and interacted more with ViaCord. So, I will go with ViaCord.
By the way, Eileen was very approachable and friendly.
I also asked her about cord tissue. She did some research and got back to me very quickly. She mentioned that for thal, cord blood is what is more relevant. cord tissue is still under research and could be used in future for bones, cartilages, etc.
