Background: Recent findings have shown that the fibrin gel derived from cord blood units (CBUs) play a significant role in wound healing and tissue regeneration. The aim of this study was to standardize the fibrin gel production process in order to allow for its regular use.
Methods: CBUs ( = 200) were assigned to 4 groups according to their initial volume. Then, a two-stage centrifugation protocol was applied in order to obtain platelet rich plasma (PRP). The concentration of platelets (PLTs), white blood cells (WBCs) and red blood cells (RBCs) were determined prior to and after the production process. In addition, targeted proteomic analysis using multiple reaction monitoring was performed. Finally, an appropriate volume of calcium gluconate was used in PRP for the production of fibrin gel.
Results: The results of this study showed that high volume CBUs were characterized by greater recovery rates, concentration and number of PLTs compared to the low volume CBUs. Proteomic analysis revealed the presence of key proteins for regenerative medicine. Fibrin gel was successfully produced from CBUs of all groups.
Conclusion: In this study, low volume CBUs could be an alternative source for the production of fibrin gel, which can be used in multiple regenerative medicine approaches.

This study presents a numerical model for incipient fibrin-clot formation that captures characteristic rheological and microstructural features of the clot at the gel point. Using a mesoscale-clustering framework, we evaluate the effect of gel concentration or gel volume fraction and branching on the fractal dimension, the gel time, and the viscoelastic properties of the clots. We show that variations in the gel concentration of our model can reproduce the effect of thrombin in the formation of fibrin clots.

Rapid control of hemorrhage is vital in first-aid and surgery. As representative of emergency hemostatic materials, inorganic porous materials achieve rapid hemostasis through concentrating protein coagulation factors by water adsorption to accelerate the coagulation reaction process, however their efficacy is often limited by the insufficient contact of material with blood and the lack of blood clot strength. Herein, we report an ultrafast dispersing and in situ gelation sponge (SG/DB) based on anchoring interface effect for hemorrhage control using freeze drying method after mixing fish scale gel (SG) and tert-butyl alcohol (TBA) pre-crystallized diatom biosilica (DB).

Epigenetic therapy has gained interest in treating cardiovascular diseases, but preclinical studies often encounter challenges with cell-type-specific effects or batch-to-batch variation, which have limited identification of novel drug candidates targeting angiogenesis. To address these limitations and improve the reproducibility of epigenetic drug screening, we redesigned a 3D in vitro fibrin bead assay to utilize immortalized human aortic endothelial cells (TeloHAECs) and screened a focused compound library with 105 agents. Compared to the established model using primary human umbilical vein endothelial cells, TeloHAECs needed a higher-density fibrin gel for optimal sprouting, successfully forming sprouts under both normoxic and hypoxic cell culture conditions.

Background: The interdental papilla plays a crucial role in the esthetic of the smile. Papilla reconstruction surgery is one of the most unpredictable periodontal procedures. This study compared the effect of the non-surgical application of a commercial hyaluronic acid (HA) gel with an autogenous gel named "albumin with platelet-rich fibrin" (Alb-PRF) on interdental papilla reconstruction.
