WASHINGTON: Researchers in Britain discovered a protein's molecular signal that apparently plays a key role in allowing newts, which are amphibians to re-grow severed limbs, a report in the journal Science says. The finding could provide insights in the field of regenerative medicine relating to mammals and humans, said Anoop Kumar of the University College London (UCL), the report's main author. Biologists have long been intrigued at how newts and other amphibians can re-grow severed limbs, never fully understanding the biological process. The protein called nAG, produced by nerve and skin cells, apparently plays a key role in stimulating blastema...

AP Science Writer NEW YORK --Researchers are trying to find ways to regrow fingers -- and someday, even limbs -- with tricks that sound like magic spells from a Harry Potter novel. There's the guy who sliced off a fingertip but grew it back, after he treated the wound with an extract of pig bladder. And the scientists who grow extra arms on salamanders. And the laboratory mice with the eerie ability to heal themselves. This summer, scientists are planning to see whether the powdered pig extract can help injured soldiers regrow parts of their fingers. And a large federally...

I grew up attending church at the Lee's Summit First Church of the Nazarene. When I was around 6 or 7 years of age, I went forward during an altar call at a revival service being held, and prayed a prayer, and then got baptised a couple of weeks later. Despite my profession of faith, my life as I grew older did not demonstrate any sort of true repentence unto salvation. All through middle school and high school, I did pretty much the same thing all the other kids did: I lied, I gossiped, I made fun of other kids,...

NHPA Tadpoles can achieve something that humans may only dream of: pull off a tadpole's thick tail or a tiny developing leg, and it'll grow right back — spinal cord, muscles, blood vessels and all. Now researchers have discovered the key regulator of the electrical signal that convinces Xenopus pollywogs to regenerate amputated tails. The results, reported this week in Development, give some researchers hope...

An immediate early publication of the journal Cell, published by Cell Press, on Nov. 22, 2006 points to the possible existence of master cardiac stem cells with the capacity to produce all three major tissues of the mammalian heart. A companion Cell paper also published online reports the discovery of a second population of cardiac progenitors, which are capable of forming both cardiac muscle and the smooth muscle found in the heart's blood vessel walls.  Together with similar findings reported in the November issue of the journal Developmental Cell, also a Cell Press publication, the findings challenge the notion that...

GAINESVILLE, Fla., June 14 (SPX) -- Regenerative medicine scientists at the University of Florida's McKnight Brain Institute have created a system in rodent models that for the first time duplicates neurogenesis - the process of generating new brain cells - in a dish. Writing in today's (June 13) Proceedings of the National Academy of Sciences, researchers describe a cell culture method that holds the promise of producing a limitless supply of a person's own brain cells to potentially heal disorders such as Parkinson's disease or epilepsy. "It's like an assembly line to manufacture and increase the number of brain cells,"...

DOCTRINE OF THE BLOOD OF CHRIST Spir Dynamics 827 4/17/96; Eph 284-286 5/11/86; Rev 11/3/82; 1 Jn 11/11/81 A. Definition and Description. 1. While our Lord did some bleeding on the cross, He didn't bleed to death, nor does His literal human blood have anything to do with the phrase found throughout the New Testament, "the blood of Christ." 2. Even Greek lexicons recognize this principle when defining the word HAIMA, the Greek word for blood. a. The Arndt and Gingrich, Greek-English Lexicon, p.22, under HAIMA in the paragraph describing the figurative use of the blood of Christ, says, "blood...

When neurologists first found a way to regrow damaged optic nerves in mammals 5 years ago, they weren't sure exactly how the procedure worked. Now, a team of researchers has identified the molecule responsible and achieved significant regeneration of optic nerves in rats without the harmful side-effects seen with some previous techniques. The optic nerve connects the eye to the brain. Injuries or diseases such as glaucoma can damage it, and once severed, nerve fibers projecting from the retina via the optic nerve don't regrow. In the past, scientists have achieved modest sprouting of these neurons in rats by inducing...

Stem cell therapy has long captured the limelight as a way to the goal of regenerative medicine, that of repairing the body with its own natural systems. But a few scientists, working in a relatively obscure field, believe another path to regenerative medicine may be as likely to succeed. The less illustrious approach is promising, in their view, because it is the solution that nature itself has developed for repairing damaged limbs or organs in a wide variety of animals. Many species, notably amphibians and certain fish, can regenerate a wide variety of their body parts. The salamander can regenerate...

April 3, 2006 — The news is being hailed as a medical milestone: Several years after receiving new bladders engineered entirely in a laboratory, seven young patients are all still healthy. It marks the first long-term success of total-organ tissue regeneration, an area of medicine that until now was more the stuff of science fiction than clinical reality. Dr. Anthony Atala, the director of the Institute for Regenerative Medicine at Wake Forest University in North Carolina, reports in tomorrow's issue of the medical journal The Lancet on the success of the new procedure, which was performed on children born with...

Appendage Regeneration in Adult Vertebrates and Implications for Regenerative Medicine Jeremy P. Brockes* and Anoop Kumar The regeneration of complex structures in adult salamanders depends on mechanisms that offer pointers for regenerative medicine. These include the plasticity of differentiated cells and the retention in regenerative cells of local cues such as positional identity. Limb regeneration proceeds by the local formation of a blastema, a growth zone of mesenchymal stem cells on the stump. The blastema can regenerate autonomously as a self-organizing system over variable linear dimensions. Here we consider the prospects for limb regeneration in mammals from this viewpoint. Department...

Researchers have discovered that certain cells inside the hair follicle are true multipotent stem cells, capable of developing into the many different cell types needed for hair growth and follicle replacement. 6 Oct 2005, 09:42 GMT - Using an animal model scientists at the Ecole Polytechnique Federale de Lausanne (EPFL) have demonstrated that these holoclones can be used for long-term follicle renewal. The researchers isolated stem cells from rat whisker follicles, labeled them and grew them in culture for 140 generations. They then implanted progeny cells into the skin of newborn mice whose hair follicles were just being formed. This...

Scientists have created a “miracle mouse” that can regenerate amputated limbs or badly damaged organs, making it able to recover from injuries that would kill or permanently disable normal animals. The experimental animal is unique among mammals in its ability to regrow its heart, toes, joints and tail.

It's a miracle: mice regrow hearts 29aug05 SCIENTISTS have created "miracle mice" that can regenerate amputated limbs or damaged vital organs, making them able to recover from injuries that would kill or permanently disable normal animals. The experimental animals are unique among mammals in their ability to regrow their heart, toes, joints and tail. And when cells from the test mouse are injected into ordinary mice, they too acquire the ability to regenerate, the US-based researchers say. Their discoveries raise the prospect that humans could one day be given the ability to regenerate lost or damaged organs, opening up a...

“To say that we are able by our own efforts to think good thoughts or give God spiritual obedience before we are spiritually regenerate is to overthrow the gospel and the faith of the universal church in all ages.” - John Owen All men can be divided into two groups. They are either regenerate or unregenerate. All men are born unregenerate (John 3:3-8). ...Spiritual darkness is in all men and lies on all men until God, by an almighty work of the Spirit, shines into men’s hearts, or creates light in them (Matt 4:16; John 1:5; Act 26:18; Eph 5:8;...

The following selection by John Calvin was taken from book 2, chapter 2 parts 18-21 of The Institutes of The Christian Religion, translated by by Henry Beveridge, Esq. A must read for all Christians who aspire to better understand the Bible's teaching on man's spiritual impotence prior to the regeneration of the Holy Spirit. 18. The limits of our understanding We must now explain what the power of human reason is, in regard to the kingdom of God, and spiritual discernments which consists chiefly of three things - the knowledge of God, the knowledge of his paternal favour towards us,...

In the beginning of this chapter, the Lord, in a vision, brings the prophet Ezekiel into a valley full of dead men's bones, quite dried and withered, and asks him the question, if he thought it possible for these dry bones to live? Thereby intimating, that although it was a thing impossible with men, yet it was easily effected by the almighty power of God. And, to convince him of it, he commands the prophet to speak to the dry bones, and to tell them, in his name, that he would make the breath of life to enter into them;...

"to open their eyes...that they recieve"acts 26v18 this verse is the grandest condensation of the propaganda of a disciple of Jesus Christ in the whole of the New Testament. the first sovereign work of grace is summed up in the words-"that they may recieve remission of sins." when a man fails in personal Christian experiance,it is nearly always because he has never recieved anything.the only sign that a man is saved is that he has recieved something from Jesus Christ.our part as workers for God is to open men's eyes that they turn themselves from darkness to light;but that is...

The False Doctrine of Baptismal Regeneration by John R. Rice   I can understand your rearing and your training. It is of a very distinctive kind, and easily recognized in the Church of Christ and Christian Church preachers and debaters. The Scriptures do make clear the answer to this problem and the Scriptures never contradict themselves. They should be taken for face value. I believe this and pray you do as well. I. "SAVED BY FAITH" IS A BIBLE DOCTRINE REFFERING TO WHAT A SINNER MUST DO TO BE SAVED 1. The Bible Does Teach That One Who Trusts in...
