Use of poly(alkylene terephthalates) and methods for their preparation

The present invention relates to poly(alkylene terephthalate) polyesters having long poly-methylene segments and their use in a wide variety of applications. Particularly, said PAT polyesters are used in biotechnological or biomedical applications, wherein the extent of cell adhesion, cell growth or cell interaction, in particular endothelial cells, depends on the odd or even number of carbon atoms in the aliphatic segments. Also provided are methods for the preparation of poly(alkylene terephthalates) (PAT) having long poly-methylene segments, wherein the bifunctional monomers, in particular terephthalic acid (or a derivative thereof) and an aliphatic diol, are dissolved in a solvent and the polycondensation reaction takes place in solution.

Tissue Equivalent Tubular Scaffold Structure, and Methods Of Production Thereof
20220176015 · 2022-06-09 ·

The present invention provides tissue equivalent scaffold structures and methods of production thereof. Such methods include providing a casting chamber comprising an elongate mould portion, axially disposing a lumen template within the elongate mould portion, and at least partly filling the casting chamber with a gel casting material comprising a matrix of fibrils or fibres and an interstitial fluid phase, such that a portion of the lumen template extends above the casting material. The fluid phase of the gel is allow to flow axially out of the elongate mould portion, in a restricted manner, thereby resulting in axial densification of the gel casting material to form a tissue equivalent tubular scaffold. Tissue equivalent scaffold structures according to the present invention are able to support cell populations both within the walls and on the surface of the construct. They have enhanced mechanical strength due to increased collagen density, and are customisable in terms of luminal diameter and wall thickness. They may find application in tubular tissue engineering.
