ACell, Incorporated is a Columbia, Maryland-based biotechnology company. The company works in regenerative medicine, in which it owns several extracellular matrix patents.[1] ACell develops, manufactures and markets products for medical and veterinary applications.[2] The company is founded by Alan R. Spievack, a former associate professor at Harvard Medical School and currently run by Patrick A. McBrayer.[3][4]

ACell's use of porcine cellular structure, called MatriStem, as a scaffold for human tissue regeneration was named the "medical breakthrough of the year" by Esquire.[5] The use of pig bladder ground up into "magical pixie dust" to regrow Spievak's brother's finger received considerable mainstream coverage.[6][7] Ken Muneoka of Tulane University, who works with ACell's scientific advisors on US-government funded investigations into regenerative medicine, said that the news should be viewed with caution because it was not a controlled study.[5]
