4. 2. Synthesis of degradable aliphatic polyesters: strategies to tailor the polymer microstructure

   Author : Jenny Fagerland; Anna Finne-Wistrand; David Kaplan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer synthesis; enzymatic synthesis; degradable polyesters; peptides; scaffolds; Chemical Engineering; Kemiteknik;

   Abstract : Key factors for successful tissue engineering are the synthesis and design of the scaffold materials. Aliphatic polyesters have been studied and often used as scaffold materials for tissue engineering. However, their lack of biological cues and degradation under high-temperature processing (e.g. READ MORE

5. 3. Hydroxyapatite – A trojan horse in the delivery of apatite-binding cytostatics in bone cancer

   Author : Yang Liu; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterials; Hydroxyapatite; osteosarcoma; Doxorubicin; Local delivery;

   Abstract : Osteosarcoma is a malignant cancer of the bone mainly affecting adolescents. Despite progress, the clinical management of osteosarcoma is still challenging. With the current chemotherapy protocol being used for more than 30 years, the number of poor responders is increasing. READ MORE

6. 4. Hyaluronan Derivatives and Injectable Gels for Tissue Engineering

   Author : Kristoffer Bergman; Tim Bowden; Jöns Hilborn; Jeffrey Hubbell; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; Hydrogel; Tissue Engineering; Scaffold; Minimally invasive strategy; Bone morphogenetic protein; Hydroxyapatite; Bone; Cartilage; Tendon; Polymer chemistry; Polymerkemi;

   Abstract : The present work describes the preparation of hyaluronan derivatives and hydrogels with potential use in tissue engineering applications. A potentially injectable hydrogel consisting of hyaluronan and collagen was successfully used to grow neurons in vitro by encapsulation of neural stem and progenitor cells. READ MORE

7. 5. Nanocellulose based 3D printed hydrogel scaffolds for cartilage and bone regeneration : Tuning of composition, pore structure and functions

   Author : Sahar Sultan; Aji P. Mathew; Lennart Bergström; Gustav Nyström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose materials; 3D printing; gradient biphasic hydrogel scaffolds; metal-organic frameworks; hydroxyapatite; cartilage and bone regeneration; osteochondral scaffolds; materialkemi; Materials Chemistry;

   Abstract : Biobased-materials with customized scaffolds have played a prominent role in the success of tissue engineering (TE). Cellulose nanomaterials (CNM) isolated from the abundant biopolymer, cellulose, is explored in this thesis for TE engineering due to its versatile properties such as biocompatibility, high specific strength, surface functionality and water retention capacity.
