Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)-based scaffolds for tissue engineering
Development and selection of an ideal scaffold is of importance for tissue engineering. Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) is a biocompatible bioresorbable copolymer that belongs to the polyhydroxyalkanoate family. Because of its good biocompatibility, PHBHHx has been widely used as a cell scaffold for tissue engineering. This review focuses on the utilization of PHBHHx-base...
متن کاملfabricating electrospun poly(3-hydroxybutyrate)/hydroxyapatite nanocomposite scaffold for tissue engineering application
. در رســاله ی حاضر، ابتدا داربست نانوالیاف سه بعدی متخلخل به روش الگوبرداری تصویری شبیه سازی شد. با استفاده از طراحی آزمایش به روش تاگوچی پس از ساخت داربست های پلی (3- هیدروکسی بوتیرات) (p3hb) شناسایی رفتار پارامترهای موادی مثل لزجت سیال پلیمر، فراریت و رسانایی الکتریکی محلول پلیمری و پارامترهای دستگاهی مثل دبی حجمی سیال، ولتاژ الکتریکی و فاصله نازل تا جمع کننده صورت گرفت. بعد از محاسبه ی خصوص...
Collagen–based scaffolds for skin tissue engineering
The aim of this study was to obtain four collagen based porous scaffolds and to assess their in vitro biocompatibility and biodegradability in order to use them for skin tissue engineering. We have prepared four variants of collagen-based biodegradable sponges by liophilization of type I collagen solution and three variants of collagen-agarose mixture in different ratios 2:1 (A), 1:1 (B) and 1:...
متن کاملAlternative block polyurethanes based on poly(3-hydroxybutyrate-co-4-hydroxybutyrate) and poly(ethylene glycol).
A series of amphiphilic alternative block polyurethane copolymers based on poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P3/4HB) and poly(ethylene glycol) (PEG) were synthesized by a coupling reaction between P3/4HB-diol and PEG-diisocyanate, with different 3HB, 4HB, PEG compositions and segment lengths. Stannous octanoate was used as catalyst. The chemical structure, alternative block arrangem...
متن کاملAdditive Manufacturing of Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)/poly(ε-caprolactone) Blend Scaffolds for Tissue Engineering
Additive manufacturing of scaffolds made of a polyhydroxyalkanoate blended with another biocompatible polymer represents a cost-effective strategy for combining the advantages of the two blend components in order to develop tailored tissue engineering approaches. The aim of this study was the development of novel poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)/ poly(ε-caprolactone) (PHBHHx/PCL) b...
