Donate Life Texas

Established by the 79th Texas Legislature in 2005, the Glenda Dawson Donate Life Texas Registry allows individuals to record legal consent for organ, eye and tissue donation after death. A non-profit organization, Donate Life Texas Inc. maintains and operates the donor registry and is governed by a Board of Directors comprised of the CEOs of Texas' three federally-designated organ procurement organizations (OPOs).

Legislation created partnerships with the Texas Department of Public Safety (TxDPS) and the Texas Department of Motor Vehicles (DMV) that allow individuals to join the donor registry when applying for or renewing their driver's license, ID or vehicle registration.

The Donate Life Texas Donor Registry was named in honor of Rep. Glenda Dawson. Elected in 2002, Dawson served two terms as the Texas House Representative for the 29th District. A kidney transplant recipient, Dawson was a passionate advocate for organ donation.

Donate Life Texas is among the fastest growing donor registries in the country. As a result, thousands of lives have been saved thanks to registered organ, eye and tissue donors.

San Antonio Eye Bank

Founded in 1965 to meet the growing need for cornea tissue in San Antonio and surrounding areas, the San Antonio Eye Bank has helped restore sight to the blind for 50 years throughout South Texas. San Antonio Eye Bank's affiliation with KeraLink International, a global network of eye banks and related programs committed to reversing corneal blindness, ensures that cornea tissue not transplanted in our community can be placed with a patient who needs it in other areas of the U.S. or the world.
GenCure applies advances in regenerative medicine to help heal patients suffering from trauma, disease or the aging process. Using processed tissue and cell-based therapies, GenCure works to connect needs with solutions.

They specialize in the collection, development and processing of a diverse range of components for human therapeutic and research applications. As a bio-medical partner, GenCure provides human cell and tissue procurement services as well as the facilities and expertise to ensure cGMP-compliant processing of materials in support of research and clinical programs.

United Tissue Resources

The former Blood & Tissue Center of Central Texas was founded in 1951 as a 501(c)(3) not-for-profit organization. The Tissue Services division was established in 1986 due to the increasing demand for allograft tissue. The Tissue Center maintained a centrally located allograft inventory for area hospitals and surgery centers serving patient needs. Approximately 4,000 tissue grafts are distributed to area hospitals annually for life-saving surgeries. Our organization also works with generous donor families to make the gifts possible. The mission continues as the organization moves forward as United Tissue Resources. United Tissue Resources' main facility is located in Austin, Texas.

Lone Star Lions Eye Bank

Lone Star Lions Eye Bank is a 501(c)(3) Texas non-profit corporation dedicated to the preservation of sight through:

  • Raising donor awareness in Central & Southeast Texas
  • The collection, processing and distribution of over 1,000 human ocular tissues annually
  • Progress in medicine through the support of research
  • The sponsorship of educational programs for the medical community and general public

Lone Star Lions Eye Bank has been operating in Central & Southeast Texas for over 40 years.
