Our Foundation of Healing

The first reported clinical application of Amniotic Membrane (AM) was for skin transplantation in 1910; however, it wasn’t until 1995 that our Chief Technology Officer, Scheffer C.G. Tseng, MD, PhD and his colleague J.C. Kim reported the use of AM for ocular surface transplantation in a rabbit limbal stem cell deficiency model.1 They found that glycerin-preserved human AM promoted corneal recovery in rabbits that would sometimes fail with stem cell transplantation alone. 

It appeared that the AM acted as a substrate to support the regeneration of corneal epithelium, just as good topsoil in the garden supports the growth of newly-planted seeds. This study suggested—for the first time—that inadequate wound healing lies in the lack of a supporting environment, and AM transplantation can serve as a surrogate niche environment to facilitate regenerative wound healing.  

Our Breakthrough Discovery

The therapeutic effect of AM is believed to originate from its innate wound healing, anti-scarring and, most importantly, anti-inflammatory properties. In 2001, when cryopreserved AM received approval for ocular surface reconstruction through Request for Designation from the Food and Drug Administration (FDA), it was recognized to promote healing through anti-inflammatory, anti-scarring, and antiangiogenic effects. 

Since that time, we have pondered the following question: What is in birth tissue that is responsible for these amazing results? One may naturally assume that AM’s complex actions are likely to be based on a symphony of biological molecules, but our cumulative research over the last decade suggests otherwise. Between 2002 and 2013, our research has focused on isolating the key molecules in birth tissue that contributes to its healing properties. We successfully identified and purified HC-HA/PTX3,2 a unique complex naturally present in AM and Umbilical Cord (UC) that orchestrates multiple anti-inflammatory, anti-scarring and anti-angiogenic effects and plays an important role in promoting regenerative wound healing as evidenced in the ocular segment.3-9

Preserving Mother Nature

We have developed a unique processing method (CryoTek®) to preserve HC-HA/PTX3 and growth factors/cytokines from the birth tissue while devitalizing living cells. In contrast, tissues processed via heat dehydration are structurally compromised and contain significantly less of the HC-HA/PTX3 complex.12,13

Our History

TissueTech was founded in 2001 as the parent entity for BioTissue Inc., which develops and markets regenerative therapies for treating the ocular surface. In 1997, BioTissue was the first company to introduce the use of cryopreserved amniotic membrane tissue for clinical application, by utilizing its proprietary CryoTek technology, proven to preserve the innate biological and structural properties of the amniotic membrane tissue.

In 2011, our company expanded from ocular space and its product offerings that, include Prokera®, AmnioGraft® and AmnioGuard® to additional market segments such as orthopedics,14-16 neuropathy,17 wound care,18-23 spine,24 urology25, and pain management26,27 using the same birth tissue products processed using our patented manufacturing technology. Our Neox® and Clarix® allografts are marketed as structural tissue products for homologous use as protective barriers and wound coverings. These products are manufactured and distributed in compliance with the regulatory requirements of 361 HCT/Ps that are regulated solely under section 361 of the Public Health Service Act and 21 CFR Part 1271.

Our Future Journey

In 2022, TissueTech has unveiled a corporate rebranding, including a name change and a new logo. BioTissue, Inc. and Amniox Medical, Inc. will now both be known under a single commercial, customer-facing entity, BioTissue, Inc. With three decades of continual advancements in regenerative medicine, BioTissue has been a clear leader in the ocular space. By adopting the BioTissue name across the entire organization, the company will also reflect that innovative heritage and promise in its surgical business, which was previously known as Amniox Medical.

BioTissue is pursuing FDA approval through submission of a Biologics License Applications (BLA) for some of our products as evidenced in a recently published Phase 2 study for complex diabetic foot ulcers.20 Our company will continue to provide sustainable health economic value, solve unmet clinical needs, and lead in technological innovation in seeking to deliver the promise of regenerative healing for our physicians and patients.
