Their research has shown that the growth of new blood vessels can be controlled by using mechanical forces in cells. This discovery is an important step towards making the cultivation of new tissue, or even organs, possible. The researchers recently published their results in the leading scientific journal PNAS. http://medicalxpress.com/news/2012-04-on-off-angiogenesis.html Medical research Fri, 27 Apr 2012 07:52:34 EST news254731943 Scientists at Duke University Medical Center have shown the ability to turn scar tissue that forms after a heart attack into heart muscle cells using a new process that eliminates the need for stem cell transplant. http://medicalxpress.com/news/2012-04-scar-tissue-heart-muscle-stem.html Cardiology Thu, 26 Apr 2012 16:00:02 EST news254665952 (Medical Xpress) -- Cancer Research UK scientists have shown that increasing pressure ejects surplus healthy cells from overcrowded tissues, revealing a possible link between this process  and the spread of cancer, according to a study published in Nature. http://medicalxpress.com/news/2012-04-scientists-cells-overcrowded-tissues.html Cancer Mon, 16 Apr 2012 06:11:43 EST news253775497 Tiny agents found in omega-3 could potentially be used to block the path of primary cancer tumours, preventing the advance to secondary stage cancers according to pharmacy researchers at the University of Sydney. http://medicalxpress.com/news/2012-04-fatty-acids-cancer.html Cancer Tue, 10 Apr 2012 09:06:27 EST news253267472 Powerful new cells created by Cardiff University scientists from cheek lining tissue could offer the answer to disorders of the immune system. http://medicalxpress.com/news/2012-03-key-immune-disease-cheek.html Ophthalmology Wed, 21 Mar 2012 11:16:42 EST news251547394 Tampere University of Technology (TUT), Finland, has been the first in the world to develop biodegradable joint implant, RegJoint.

When Morrow, assistant professor of biology, recently asked the class how to find the mutation behind a disease, a hand shot up in the back of the class to signal the answer: "Sequence the patient's genome." http://medicalxpress.com/news/2011-12-gene-mouse-neural-retina-sequenced.html Genetics Wed, 07 Dec 2011 13:06:36 EST news242485568 Idiopathic Pulmonary Fibrosis (IPF) is an incurable disease in which the delicate gas exchange region of the lung fills with scar tissue, which interferes with breathing.

After injury to the central nervous system (CNS), neurons are lost and largely replaced by a scar often referred to as the glial scar based on its abundance of supporting glial cells. Although this process has been known to science for over a century, the function of the scar tissue has long been disputed. However, there are indications that it stabilizes the tissue and that it inhibits the re-growth of damaged nerve fibres. http://medicalxpress.com/news/2011-07-unexpected-cell-spinal-cord.html Medical research Thu, 07 Jul 2011 14:00:16 EST news229265809 Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off. http://medicalxpress.com/news/2011-06-enzyme-important-aggressive-breast-cancer.html Genetics Thu, 30 Jun 2011 13:37:13 EST news228659818 Changes in the ability of lung cells to divide may play a role in initiating or prolonging lung tissue inflammation, a hallmark of chronic obstructive pulmonary disease (COPD), according to a study conducted by researchers in France. http://medicalxpress.com/news/2011-05-cell-division-abnormality-contributes-inflammation.html Diseases, Conditions, Syndromes Sun, 15 May 2011 11:23:29 EST news224677389 All of the tissues and organs of the body arise from one of three embryonic precursors: the ectoderm, mesoderm and endoderm. The ectoderm contributes to several tissues, including the nervous system and the skin, but some studies have suggested that development into neurons requires nothing more than the absence of specific inhibitory signals.  http://medicalxpress.com/news/2011-05-brain.html Neuroscience Fri, 13 May 2011 10:50:23 EST news224502607 If pending clinical trials prove successful, a new discovery published in The FASEB Journal could represent a major scientific leap toward human tissue regeneration and engineering. In a research report appearing online, Yale scientists provide evidence to support a major paradigm shift in this specialty area from the idea that cells added to a graft before implantation are the building blocks of tissue, to a new belief that engineered tissue constructs can actually induce or augment the body's own reparative mechanisms, including complex tissue regeneration. http://medicalxpress.com/news/2011-05-scientists-method-human-tissue-regeneration.html Medical research Thu, 12 May 2011 16:32:51 EST news224436750
