Hence acellular scaffolds from rat's abdominal aorta was developed and implanted to reconstruct rat's carotid artery. Without any cell seeding, the grafts were patent and their inner lumen was covered with endothelial cells after implantation. The fourth grafts were for the regeneration of peripheral...
Eventually, those organs may be repaired or treated while on the machine – harmful fat could be removed from a liver, for example. This approach was first developed for lungs – a device was just approved in the U.S. that keeps lungs breathing outside of the body – and is used in ...
the heart and even skin are all organs. A human actually has two circulatory systems: a short loop running from the heart to the lungs and back, called the pulmonary system, and the systemic circulatory system, which runs from
In order to graft big structures it is necessary that the organ or tissue produced "ex vivo" bears a vascular tree to ensure the nutrition of its deep layers. At present, no technology has been developed to provide this vascular tree to TE derived products. Thus, these tissues must be ...
Which of the following organs has erectile tissue? A. Mammary gland B. Vagina C. Uterus D. Clitoris E. Ovary What are the Parts of the Female Reproductive System?: The female reproductive system provides women with the structures and organs needed ...
farther away. Cells ‘read’ these gradients to figure out their position and role in the developing tissue. For example, high levels might tell a cell to become a nerve cell, medium levels tell it to become a skin cell, and low levels might signal a cell to become connective tissue. ...
The olfactory organs are particularly well developed in gymnophionans, and, on each side, distinct dorsal and ventral olfactory nerves reach the bulbs (Fig. 1). The olfactory bulbs of amphibians evaginate from the rostral telencephalic wall and secondarily form the main (MOB) and the accessory...
In the more highly developed animals, such as humans, what gas is used to regulate the activity of the heart, the blood vessels, and the respiratory system? Collecting and returning fluid to blood as well as defense against infection and tissue damage are the main functions of the ___...
a team from the Center for Brain Injury and Repair at the University of Pennsylvania developed tissue-engineered nerve grafts (TENGs) to “bridge” missing nerve segments and facilitate regenerative capacity. Using porcine neurons and axon ...
An automated system that uses robots has been designed to rapidly produce human mini-organs derived from stem cells. Researchers at the University of Washington School of Medicine in Seattle developed the new system. The advance promises to greatly expand the use of mini-organs in basic research ...
