  1. 11. 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

    Författare :Shubham Jain; Anna Finne-Wistrand; Kamal Mustafa; Mikael Hedenqvist; Lauren Flynn; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Yang Sun; Anna Finne-Wistrand; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tissue engineering; nanodiamond; scaffold; bioreactor; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : 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. LÄS MER

  5. 14. Towards molecular weight-dependent uses of kraft lignin
