Dramatic advances in the fields of biochemistry, cell and molecular biology, genetics, biomedical engineering and materials science have given rise to the remarkable new cross-disciplinary field of tissue engineering. Tissue engineering uses synthetic or naturally derived, engineered biomaterials to replace damaged or defective tissues, such as bone, skin, and even organs.
Move over, salamanders, we humans can also regrow some of our body tissues. At least, this is what a new study published on October 9, 2019, in the journal Science Advances, reports. Using a mechanism quite similar to that by which amphibians like salamanders, and some zebrafish, grow back lost body parts, human joint cartilage can also regenerate itself.
A microelectrode array is an implantable device through which neural signals can be obtained or delivered.
A team of Tufts University-led researchers has developed three-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, a significant advancement for the study of brain tumor biology and pharmacological response.
Using light to facilitate the formation of new blood vessels: it is the breakthrough outcome of a research study carried out by researchers at Istituto Italiano di Tecnologia in Milan (Italy). The study was published in Science Advances.
Organs, muscles and bones are composed of multiple types of cells and tissues that are carefully organized to carry out a specific function.
Labnatek launches the first Polish company delivering additive technologies and high-resolution imaging techniques for the biotech and the healthcare sectors.
Damage to the meniscus is common, but there remains an unmet need for improved restorative therapies that can overcome poor healing in the avascular regions.
Mast cells are critically involved in immunity and immune disorders. However, they are rarely cultured ex vivo for experimental manipulation because of the difficulty in isolating useful numbers and limitations related to 2D culture.
Imagine a perfectly biocompatible, protein-based drug delivery system durable enough to survive in the body for more than two weeks and capable of providing sustained medication release.
As the global demand for tissue and organ transplants significantly outstrips supply, tissue engineering might provide a potential solution. But one of the significant challenges in tissue engineering is growing tissue in 3D, and the scaffolds used to position cells to develop tissue-specific functions are often challenging or prohibitively expensive to develop.
Traumatic brain injury (TBI) –– defined as a bump, blow or jolt to the head that disrupts normal brain function –– sent 2.5 million people in the U.S. to the emergency room in 2014, according to statistics from the U.S. Centers for Disease Control and Prevention.
Scientists have come up with a very rapid 3D printing technique for producing the most complex tissue forms in hydrogels which are loaded with stem cells, and then generating the growth of blood vessels in the resulting tissue mass.
Writers know the power of the pen, but scientists are just discovering its secrets.
Bioengineers and dentists from the UCLA School of Dentistry have developed a new hydrogel that is more porous and effective in promoting tissue repair and regeneration compared to hydrogels that are currently available.
A team of researchers including those from Biotechnology Center of the TU Dresden (BIOTEC), have found that stem cells could be used for several forms of tissue engineering including tooth repair.
Stem cells hold the key for tissue engineering, as they develop into specialized cell types throughout the body including in teeth.
Researchers have developed a new 3D bioprinting method that can produce any part of the heart, from tiny capillaries through to full-scale heart components.
Today the U.S. Food and Drug Administration announced a comprehensive policy framework for the development and oversight of regenerative medicine products, including novel cellular therapies.
Scientists can turn proteins into never-ending patterns that look like flowers, trees or snowflakes, a technique that could help engineer a filter for tainted water and human tissues.
Cells equipped with superparamagnetic iron oxide nanoparticles can be directed to a specific location by an external magnetic field, which is beneficial for tissue repair.
