NAMSR- Medical News: Synthetic Blood Vessels developed using 3-D printer

Researchers at Boston's Brigham and Women's Hospital are using a 3-D bioprinting method to create functioning synthetic blood vessels that could be used in the near future for developing transplanted tissues and testing drugs outside of the body.

 
PRLog - Jun. 23, 2014 - ARLINGTON, Va. -- The research team printed a 3-D mold of the blood vessels, comprised of naturally occurring agarose fiber; it is then covered with a hydrogel (jelly-like substance). They were able to create vessels by removing the mold from its hydrogrel cast--without harming the surrounding cells.

"What is unique about our approach is that the fiber templates we printed are strong enough that we can physically remove them to make the channels," said researcher and biomedical engineer Ali Khademhosseini. "This prevents having to dissolve these template layers, which may not be so good for the cells that are entrapped in the surrounding gel."

Researchers say the artificial vascular network enhanced the surrounding cells transportation systems, viability and differentiation. The team was then able to get the vessels to exhibit an endothelial monolayer; this is the lining of cells that forms the interior of blood vessels, demonstrating the network's superiority.

Synthetically created transplants may not be in the very near future; however the use of such artificial biological systems for drug development research is a realistic intermediary until then. Companies like Organovo are already active in this arena, and tout the technique's cost savings methods compared to animal studies, which don't always provide as accurate information about the human interactions. Organovo has turned their attention to liver cells for toxicity testing for now, but the technology developed by researchers at Brigham and Women's Hospital could be applied to tissues for any part of the body.

"Engineers have made incredible strides in making complex artificial tissues such as those of the heart, liver and lungs," Khademhosseini said in the statement. "However, creating artificial blood vessels remains a critical challenge in tissue engineering. We've attempted to address this challenge by offering a unique strategy for vascularization of hydrogel constructs that combine advances in 3D bioprinting technology and biomaterials."

CANDIDATES WHO WANT TO BREAK INTO MEDICAL SALES:

RMSR® Medical Sales Certification offered by the National Association of Medical Sales Representatives is designed for entry level medical device sales reps. The course covers a wide array of topics pertaining to industry knowledge that candidates need to acquire before applying to medical sales positions.

The course and training helps to develop the industry skills, maximizing the candidates’ potential and goals, as well as making them feel valued and stimulated in their role when communicating with members of the medical community. By an applicant acquiring medical sales training and a RMSR Certification, it puts him/her in a position of strength and qualifies them for medical sales jobs. Medical knowledge is key in this industry and when communicating with doctors, surgeons, and nurses etc. It is extremely important for representatives to use key terminology pertaining to the medical product he/she will be promoting. The only way to succeed in this industry is to garner actual sales. Doctors and Surgeons will not acknowledge a Sales Rep who is not proficient in essential medical terminology, knowledgeable of medical devices/equipment and the anatomy. For those lacking a solid sales background the RMSR course covers knowledge of medical selling techniques and regulation such as Effective Territory Management, Effective Networking, Medical Sales Ethical & Regulatory Guidelines and more.

The National Association of Medical Sales Representative™ (NAMSR) is the largest professional association in the world for Medical Sales Representatives. Through our numerous members, the NAMSR™ provides accredited training, continuing education, information about the industry, up-to-date news, programs to assist medical sales reps in their work, training programs to assist candidates who want to break into the industry and initiatives to improve communication with the medical sales field.
