2. 1. Composite Regenerative Scaffolds

   Author : Elle Edin; Jöns Hilborn; May Griffith; Alicia El Haj; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nerve; neurite; regeneration; PEDOT; PEDOT:Tosylate; electrostimulation; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Abstract : Regenerative medicine and tissue engineering solutions of heavily innervated tissues are at this point lacklustre. This thesis expands our knowledge of appropriate acellular scaffolds for tissue repair in general and nerve regeneration in particular. READ MORE

4. 2. Porous degradable polyester scaffolds

   Author : Peter Plikk; Ann-Christine Albertsson; Johan Lind; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; copolymer; porous scaffold; ring-opening polymerization; electron beam; gamma irradiation; Polymerteknologi; Chemistry; Kemi;

   Abstract : Tissue engineering is a growing research field in which degradable porous scaffolds are used to regenerate tissue from the patients own cells. The problems due to donor shortage or the lack of full property restoration from prosthetic implants can thereby be overcome. READ MORE

5. 3. 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.

6. 4. Engineering 3D degradable pliable scaffolds for adipose tissue regeneration : Advancing cell-material interactions by understanding the influence from thermal, chemical, mechanical properties and scaffold design

   Author : Shubham Jain; Anna Finne-Wistrand; Kamal Mustafa; Mikael Hedenqvist; Lauren Flynn; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradable polymers; 3D scaffolds; adipose tissue regeneration; cell-material interaction; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : In soft tissue defects that arise due to trauma, tumor resections and complex burns, a significant loss in adipose tissue remains a considerable challenge due to the insufficient regenerative capacity of the tissue. This thesis focuses on assessing cell-material interactions between degradable 3D polymer scaffolds with different designs and adipose tissue-derived stem cells. READ MORE

7. 5. Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications

   Author : Marlene Munoz; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biopolymers; polyhydroxyalkanoates; polyhydroxybutyrate; moderate halophile; Halomonas boliviensis; fermentation; recovery; thermally induced phase separation; scaffolds; covalent modification; hydrophobic ion pairing; polyethylenemine; lysozyme.;

   Abstract : Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based polymers in a large variety of applications. READ MORE
