  2. 1. The role of computer-aided design and surface chemistry on Cell-scaffold interactions

    Author : Sun Yang; Anna Finne-Wistrand; Ann-Christine Albertsson; Jinshan Pan; My Hedhammar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amorphous degradable copolymer; aliphatic polyester; 3D fiber deposition; computer-aided design; Tween 80; BMSC; hOB; porous scaffolds;

    Abstract : Cell interactions and cell response to three dimensional scaffolds based on poly(L-lactide-co-1,5-dioxepan-2-one) [poly(LLA-co-DXO)] and poly(L-lactide-co-e-caprolactone) [poly(LLA-co-CL)] wereimprovedstudiedby increasing surface hydrophilicity and by using computer-aided scaffold design. Different amounts of Tween 80 (3, 10, 20 wt%) were mixed with the copolymer and it was found that the water contact angle decreased significantly with the amount of Tween 80. READ MORE

  4. 2. Engineering and Functionalization of Degradable Scaffolds for Medical Implant Applications

    Author : Yang Sun; Anna Finne-Wistrand; Ann-Christine Albertsson; Minna Kellomäki; KTH; []

    Abstract : The treatment of bone defects is facing the situation of lacking donations for autotransplantation. As a valid approach, scaffold-based tissue engineering combines the construction of well-defined porous scaffolds with advanced cell culturing technology to guide tissue regeneration. READ MORE

  5. 3. Investigation of the Freeze-Thawing Process for Pharmaceutical Formulations of a Model Protein

    Author : Anna Hillgren; Jörgen Tegenfeldt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Physical and Inorganic Pharmaceutical Chemistry; fysikalisk och oorganisk farmaceutisk kemi;

    Abstract : Recent advances in recombinant DNA technology have resulted in a great number of proteins with a potential to enter pharmaceutical formulations. The most commonly used method for preparing protein pharmaceuticals is by freeze-drying. READ MORE
