... tissue engineering There is increasing interest in fabricating porous or foam structures due to many benefits introduced by the interconnected micropores inside the structures, such as low density, low thermal conductivity, high surface area, and efficient stress transmission. By making use...

... stress, the optimal moving speed of the dispensing head is determined from the flow rate of the scaffold material dispensed. Experiments were also carried out to illustrate the effectiveness of the model developed. Griffith , L. G. , and Naughton , G. , 2002 , “ Tissue Engineering-Current...

...L. Shor; S. Güçeri; M. Gandhi; X. Wen; W. Sun, Ph.D. Bone tissue engineering is an emerging field providing viable substitutes for bone regeneration. Freeform fabrication provides an effective process tool to manufacture scaffolds with complex shapes and designed properties. We developed a novel...

... tissue engineering Cautery, or the coagulation of tissue, is a surgical technique that has long been used to denature proteins and minimize bleeding during surgical procedures ( 1 ). One method to perform cautery is electrosurgery, which uses radio frequency (rf) electrical currents to actively...

...Byung Kim, MS; Intae Kim, MS; WooSeok Choi, BS; Sung Won Kim, M.D., Ph.D.; JooSung Kim, M.D., Ph.D.; Geunbae Lim, Ph.D. Traditional approaches in tissue engineering are limited in that cell seeding is inefficient and cells cannot be located on a scaffold precisely. Moreover, the traditional methods...

... are closely associated with MR signal characteristics. Our results indicate that the contrast-based MRI is a safe and noninvasive method of monitoring engineered tissue implants in vivo . This imaging method may be useful for preclinical and clinical studies in tissue engineering. Mironov , V...

Chrisey Biomaterial direct-write technologies have been receiving more and more attention as rapid prototyping innovations in the area of tissue engineering, regenerative medicine, and biosensor∕actuator fabrication based on computer-aided designs...

... ends spanning across the lesion gap is defined as a bridge or bridging substrate. A bridge can be constructed from biomaterials, cells, and/or tissues, or a combination of biomaterials and cells based on tissue-engineering concepts ( 1 2 3 4 ). Some bridges were shaped into guidance channels...
