What makes us different?
Consistent with our mission to prioritize clinical convenience, practicality, and effectiveness, there were numerous considerations incorporated into the design of our product lines. From the packaging it is stored in, to the shape it is configured in, it all relates to optimizing its suitability for use and potential for clinical benefit. But, FIRST AND FOREMOST, our products were developed with design requirements for safety, and products provided are verified to satisfy these requirements.
What sets Seed Biotech apart is our Process. We use precise methods to get measurable results and thereby create better biologic products. We have shown a greater than 95% reduction in DNA using our proprietary decellularization process.
Under the guidance of clinical and industry experienced experts, Seed Biotech’s core competency is based on a novel decellularization and stabilization process which is conducted in a quality by design facility with advanced operational support systems.
Seed Biotech is uniquely able to optimally prepare highly variable biological materials through a dynamic purification process that depletes biomaterials of cells and cellular contents without imparting unintentional alterations to the extracellular matrix comprised of soluble and non-soluble bioactive constituents. It is this technology that uniquely positions Seed Biotech as an industry leader in innovation and a manufacturer of high quality products.
Reducing the Risks for Disease Transmission from Residual Donor DNA
There is an inherent time delay between the first presentation and point in time when a communicable disease is regarded as a risk to the general population and when a state of national/global awareness of that communicable disease will exist. Donors could potentially carry communicable diseases even through currently required and exhaustive screening and testing, as such testing would be ineffective because it would not be done on the current disease.
As such, Seed Biotech purifies donated tissue materials depleting them of cell and cellular contents and batch verifies the material as suitable for use without alteration or loss to the quality of the native extracellular matrix material. It has been shown that the presence of residual DNA of donor in allograft tissues is correlated with increased inflammation occurring as part of the natural would healing process, as well as increased fibroblast activity, which is recognized to be associated with fibrotic tissue formation. Seed Biotech has established and recognizes the criticality of an effective decellularization process of donated human tissues for clinically used products. Seed Biotech’s proprietary processing methods surpasses the current leading manufacturers by providing a better safety profile and demonstrates an increased clinical advantage for patients.1
In addition to the possible transmission of a communicable disease, other effects of residual DNA include chronic inflammation and undesirable fibroblast activity.2
Measurement of Clinical Benefit Potential
Seed Biotech’s decellularization process preserves the clinically relevant properties regarded to be related to the quality and effectiveness of the end products. The pursuit of knowledge regarding the mechanisms of action of tissue products was equally prioritized throughout both the process and product development. The process used to manufacture donated human placental tissue has been verified through studies to preserve the surface chemistry, architecture, composition, geometry, and organization of the extracellular matrix (ECM) of the material, ss well as the preservation of the ECM soluble constituents, but more importantly post-process preservation of the numerous critical properties of the ECM.
Such properties are recognized to be critical to cell activity and tissue cascades 2,3,4,5,6,7,8. The ECM of connective tissues acts as a reservoir of bioactive peptides including TIMPS, growth factors, cytokines, and glycosaminoglycans and the basement membrane interface acts as a substrate that supports cellular adhesion, transplanar migration, and proliferation. Proper preparation and preservation of properties unique to neotenic tissues can be used for potential clinical benefit.3,8 Seed Biotech’s innovations are driven by a focus on improving clinical outcomes, specifically the reduction of secondary clinical symptoms common to surgical intervention, such as infection, loss of ROM due to fibrosis, and vascular tissue injury, while improving the quality of tissue regeneration. Seed Biotech further hopes to contribute by working with clinicians in bringing technologies to market to address clinical scenarios and conditions that currently remain very challenging.
