SUGAR LAND, Texas – A Sugar Land biopharmaceutical company is the first in the nation to receive FDA approval or a trial to treat COVID-19 long haulers with adult stem cells. Long haulers are patients who are no longer infected with coronavirus but suffer the harsh symptoms sometimes for months after. “We just don’t know how well they work in COVID long haulers. Hope Biosciences then uses a patented media, or food source, that eventually grows one billion of the patient’s stem cells that will be injected back into their body. “I think that’s what these COVD-19 long haulers want,” Chang said.
