Technology


ACell’s patented core technology, MatriStem UBM™ (Urinary Bladder Matrix), is the only commercially available form of urinary bladder matrix. UBM appears to facilitate the body’s naturally adaptive or accommodative immune response, which is conducive for wound healing and three-dimensional growth of various cell types.1 In the presence of UBM, in pre-clinical studies, the body has been observed to:

  • Angiogenesis1 and innervation2
  • Modulation of the inflammatory response1
  • Participation of autologous progenitor cells3,6
  • Resistance to infection5
  • Host deposition of functional, site-appropriate tissue4,6,7
