It is a question people have been asking forwell-- ages. Is there a way to turn back the aging process in people?

For centuries, people have been looking for a fountain of youth. The idea is that if you find a magical fountain, and drink from its waters, you will not age.

Spanish explorer Juan Ponce de Len searched for waters with magical powers in the early 1500s. But what he found instead is the American state of Florida.

Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus.

The hypothalamus is part of your brain. It controls important activities within the body. They include growth, reproduction and the way we process food.

Researchers at New Yorks Albert Einstein College of Medicine found that hypothalamus neural stem cells also influence how fast aging takes place in the body.

What are stem cells? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.

Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature.

Cai explains what they found.

"Aging speed is controlled, can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells. I think these findings are quite interesting, potentially even remarkable."

He adds that when the hypothalamus starts aging, so does the body.

"So when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost, it eventually leads to aging."

Using this information, the researchers began trying to activate, or energize, the hypothalamus in laboratory mice. They did this by injecting the animals with stem cells.

Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination of the animals muscles. They also studied the social behavior and cognitive ability of the mice.

The researchers say the results show that the treatment slowed aging in the animals.

Cai says injecting middle-aged mice with stem cells from younger mice helped the older animals live longer.

"When we injected the hypothalamus stem cells, which were derived from young mice, we injected them to the middle-aged mice and that was, in fact, to slow down aging. So the mouse aged slowly and they also have increased their lifespan, which is longevity."

But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings.

"If we can translate what we have seen in animals to humans, I think humans, they can function better during later ages, later stage of aging."

Cai and his team say their studies may have other benefits. They say the findings could lead to new ways to help doctors identify and treat any number of age-related health issues.

A Breakthrough approach to skin rejuvenation ProCell Therapies brings together professional Dermabrasion & Microchanneling technology with Stem Cell science and the Procell device for an exciting new approach to skin rejuvenation.

Clinical studies prove that this breakthrough treatment achieves better results with shorter recovery time than far more invasive & expensive procedures such as fractional lasers and deep chemical peels for fine lines, scars, acne, acne scarring, sun damage & laxity.

ProCell Therapies are the perfect complement to facial fillers, neurotoxin injections, and deeper skin tightening procedures, like fractional CO2 resurfacing and RF microneedling.

How does Procell Work?Dermabrasion & Microchanneling with Procell stimulates the basal layer of the epidermis that produces keratinocytes to increase production of new collagen and elastin through the release of growth factors and cytokines. Unlike more aggressive treatments like fractional lasers and chemical peels that injure the skin to cause a healing response, Procell triggers the gene expression of growth factors, peptides and cytokines with minimal to no damage to the dermis. These sophisticated, organic, autologous electro-chemical compounds increase production of collagen and elastin for firmness, elasticity, and texture & tone. Procell works wonderfully in combination with microdermabrasion. Livra Stem Cytokine serums are applied during and after treatment to penetrate the skin and deliver high concentrations of growth factors that enhance production of healthy new skin.

Unlike growth factor serums made from other sources, Procells Livra serums are derived from mesenchymal stem cells that produce the full array of peptides, growth factors and cytokines specifically for regeneration of healthy, new skin!.

Going bald is a worry thatcrosses many people's minds at least once intheir lives.

Unless you are super cool and look like Michael Jordan, Zinedine Zidane or Bruce Willis, losing your hair can be a traumatic experience.

Studies have shown that bald men are more intelligent, but it's still a hard thing to live with if you're attached to your flowing locks.

At least 50 per cent of men will experience some form of baldness in their lifetime.

This can be cause by all sorts of things, ranging from age to genetics, illness and hormones.

For many it will happen before they reach their fifties, but for some it could even start occurring as early as their twenties.

If you feel that you are starting to bald however, new research might have just answered your prayers.

The good folks overat the University of California have been conducting studies on mice and have discovered a new way to make hair grow.

By increasing the production of lactate in hair cells, previously redundant follicles have appeard tostart growing again.

The study has been published by Nature,and showed that hair cells are quitedifferent to the other skin cells in the body.

These cells produce something called pyruvate, which is a glucose that if sent to the 'powerhouse of the cell' (the mitochondria) can actually help hair grow.

Heather Christofk, the co-author of the study is quoted as saying:

Our observations about hair follicle stem cell metabolism prompted us to examine whether genetically diminishing the entry of pyruvate into the mitochondria would force hair follicle stem cells to make more lactate, and if that would activate the cells and grow hair more quickly.

They carried out their theory on two sets of mice, one that had been engineered to not produce lactate and one that had been engineered to produce lactate.

The grop that waslackinglactatestruggled togrow hair, while the group withmore lactate actually saw an increase in hair growth.

William Lowry, another author on the study, adds:

Before this, no one knew that increasing or decreasing the lactate would have an effect on hair follicle stem cells.

Once we saw how altering lactate production in the mice influenced hair growth, it led us to look for potential drugs that could be applied to the skin and have the same effect.

The scientists have now managed to identify two different drugs which could help humans suffering from hair loss.

These are called RCGD423 and UK5099, which both help hair produce lactate - but we should stress that these haven't been tested on humans.

Aimee Flores, a predoctoral trainee who is credited as the first author on the study, says:

The idea of using drugs to stimulate hair growth through hair follicle stem cells is very promising given how many millions of people, both men and women, deal with hair loss.

I think we've only just begun to understand the critical role metabolism plays in hair growth and stem cells in general; I'm looking forward to the potential application of these new findings for hair loss and beyond.

What's even better is that if the research and drugs turn out to be a success, it could be used to help those who suffer fromalopecia, the hair loss condition which effects two in every1,000 people in the UK.

Jack Massey is ready to go back to school.

Only this time, the University of Florida senior will head back to campus with his mom and a new outlook on life.

Massey suffered a spinal cord injury in a pool accident in March and is paralyzed from the chest down. After months of rehab, he's eager to get back into a familiar routine.

"It's definitely boring," the 21-year-old said at his parents' home in Niceville. "There's not a lot to do. I want to go back to school. I still have my brain. I still have everything I need to be successful."

After the accident March 17, Massey was treated at the University of Florida Shands Hospital and then was transferred to Shepherd Center, a spinal cord and brain injury rehab center in Atlanta. At Shepherd Center he met with a peer mentor, counselors and physical therapists to help him find a new normal.

Jack has remained positive throughout the past six months.

"Jack has been a fighter through all of this," said his mother, Julie. "I think he's done well. I only saw him break down once."

Before the accident, Jack was a well-rounded athlete who playing baseball and basketball and ran. He was a star on the track and field team at Niceville High School, with his 4 X 800 relay winning state his senior year.

He says the biggest challenge now is not being able to do the same things he could before.

"I can't get up and go," he said. "It didn't really start to set in until after I got out of rehab."

Jack has had to find enjoyment in other things, like reading or playing with the dogs. His friends have learned to transfer him from his wheelchair to a car so they can take him to the movies or out to eat. When they recently took a trip to the beach, Julie said five of Jack's friends carried him out to the sand a lesson on how hard it is to navigate the world in a wheelchair.

Jack said he believes technology one day will advance enough that he won't be paralyzed forever. He also volunteered to do stem cell surgery to allow doctors to study the effects of stem cells on his spine for the next 15 years. Instead of wallowing in self-pity, he's moving forward. But he'll need help.

"I'm appreciating everything in the now," he said.

Doctors have said Jack has adapted faster than expected, but there are still some everyday essential tasks that are out of his reach. He cannot write or cook. He can shower himself but can't dry himself or transfer himself in and out of his wheelchair. The Massey family hopes to secure a personal care attendant for Jack at school, but until then Julie will be in Gainesville to help him transition. An occupational therapy student from the university will also help Jack on a temporary basis.

Finding proper care for her son has proven to be a learning experience for Julie and her husband, Lance.

"I don't know how people do it," she said. "We have good health care, but then there's hidden costs. There's travel expenses. ... It's kind of humbling. Nobody should have to go to GoFundMe for medical help."

Jack wants to spend his final year as an undergrad as independent as possible. After months of helping him recover, Julie said it will be hard to let her son go. Jack is the oldest of three; his brother Lance is 19 and a student at UF and his sister Alina is 14 and attends Ruckel Middle School.

"It's like letting him go off to kindergarten again," she said.

As for life after college, Jack said he doesn't feel limited in career choices. One of his professors in the geology department encouraged him by saying that there were plenty of opportunities he could pursue in that field. Jack said he may also consider law school. One thing he's learned through this life-altering experience is that there are no limits to what he can achieve.

"I haven't done that much deep thinking. I just go with the flow," he said. "But I learned I have more perseverance. I'm more mentally tough than I thought I was. I'm appreciative for life in general. That's one of the big things."

It will take you just a few hours to donate stems cells but it will save someones life as it is usually the last or the only resort for those suffering from blood cancer. Stem cells are undifferentiated biological cells that can grow into specialized cells. There are two types of stems cells, which are embryonic stem cells and adult stem cells. Embryonic stem cells are extracted from theblastocyst, which is a structure that contains cell mass that develops into an embryo. Adult stem cells are the undifferentiated cells that replenish the dying cells or repair the damaged cells. These adult stems cells are donated during the stem cell donation. Stems cells are transferred to the patient, where it differentiates into healthy specialized cells. (ALSO READMajor blood types and who can donate blood to whom).

Stem cell donation is voluntarily donating the stem cells produced by your body. It can be donated in two ways. The first method is called Peripheral blood stem cell (PBSC) donation while the other method is bone marrow donation. Bone marrow donation requires hospitalization. Bone marrow is collected from your pelvis by doctors under general anesthesia using a syringe. You may experience pain and bruise but you will recover within a week.

Peripheral blood stem cell donation is used by 90 percent of the people to donate stem cells. It is an easy and quick process to collect the blood-forming cells found in the circulating blood. This non-surgical process of collecting the stem cells is called apheresis.

You need to register to donate stem cell. Your cell sample from cheek is analyzed for HLA typing and when there is a requirement for stem cell with your HLA type, you will get a notification. A complete health check-up is carried out to ascertain that you are fit to donate the stems cells. Once the check up is done, you will be given an injection called GCSF (Granulocyte Colony Stimulating Factor)to increase the stem cell present in your blood. This injection will be administered for five days and on the fifth day, the stem cells are collected. A tiny tube will be inserted in your arm and this tube is connected to a machine that will collect the stem cells. Your blood will pass through the machine. This procedure usually takes about five hours. You may experience flu like symptoms after donating the stem cells but it will soon subside.

Your cells will be given to those suffering from blood cancer and it could save the life of that person.

There are many claims that stem cells possess anti-ageing properties and other secrets to youth and regeneration. However, there has not been much scientific proof demonstrating these touted abilities.

Dr Paul Lucas, an assistant professor of orthopaedics and pathology from the New York Medical College in the United States, notes that the words stem cells are thrown around far too casually, and that many people assume that they are a single type of cell.

The definition of stem cell is an operational definition.

That is, it describes what the cell can do, and not any particular protein or other marker it can make, he says.

According to him, a stem cell is a cell that can:

Differentiate into at least one phenotype (cell type), and

Has the ability to divide, with at least one daughter cell remaining a stem cell.

Lots of hype, very little biology. I have written several answers on the website Quora that address this.

Pills and creams are not legit.

The skin has a barrier called the stratum corneum that prevents bacteria from getting inside the body.

The stratum corneum will also block stem cells, which are much, much larger than bacteria, in the form of a cream.

Any stem cell will not survive in a pill with no water. And of course, any cell will not survive the hydrochloric acid in the stomach.

So there is no way stem cells in either a pill or a cream can get inside the body.

Even if a stem cell could get inside the body, there is very little data that any stem cell will be anti-ageing its a way to separate people from their money.

There are several reasons stem cells do not counter ageing.

Stem cells are not magic. They are not magic pixie dust you can sprinkle on everything and make it be perfect.

Ageing has many causes. One of them is DNA and cellular damage.

It is thought that the various adult stem cells are the cells of origin of cancer. The data is very solid for at least hepatomas and leukaemias.

That means that stem cells can suffer mutations that alter cellular function degrading it in some cases, and causing it to go haywire and be cancer in others.

Also, how are stem cells to be injected? Into each tissue? Every muscle, organ, tendon, ligament, etc?

Or are the stem cells to be injected into a vein and travel to all parts of the body?

There are two technical problems with this:

Injecting into a vein means that most of the cells are going to be trapped in the lungs before they go out to the rest of the body, as our veins all lead first to our heart, then our lungs.

Blood vessels are sealed tubes. Think pipes.

Just how are the stem cells supposed to exit the pipes?

This is especially true for reversing ageing in the most important organ the brain.

The neural tissue in the brain is separated from the blood vessels by another layer of tissue called the blood-brain barrier.

Even if stem cells got out of the blood vessels in the brain, they are not going to get to the neural tissue, which is the tissue that needs to rejuvenate.

There is no way any injected stem cells are just going to magically replace all the aged cells in the body.

Stem cells are a class of undifferentiated cells that are able to differentiate into specialised cell types. Photo: 123rf.com

Plants are very different from us. No cell from a plant is going to be able to incorporate into our tissues and act like a stem cell.

Many mammalian stem cells particularly mesenchymal stem cells synthesise and secrete several proteins.

Some of these proteins are growth factors in that they cause other cells to divide.

The claim seems to be that plant growth factors will have the same effect on human cells as they do on plant cells.

That is false.

Even some of the skincare people admit this. The following quote is from the website of a US-based skincare company that uses both human and plant stem cells: That said, unlike human stem cells, the growth factors, cytokines and other proteins, which are the products of plant stem cells, do not have the ability to act in the same way in humans, as in plants.

Plant stem cells communicate in a different biochemical language that human cells do not recognise.

First is the source.

ESCs are the inner cell mass of a five to seven-day-old blastocyst, which is formed after the sperm successfully fertilises the egg.

PSCs come either from the tissue of the placenta itself or from the Whartons jelly of the umbilical cord.

Secondly, ESCs are pluripotent, meaning they are able to differentiate into every tissue of the body. They can also form tumours in our body.

PSCs are essentially adult stem cells that have limited proliferation potential, i.e. the cell has a fixed number of times it can divide before it dies. They are multipotent, meaning that they have the ability to form more than one cell type, and do not form tumours.

Probably less costly, but no more effective.

The treatment uses mesenchymal stem cells (MSCs).

The discoverer of MSCs Prof Dr Arnold Caplan says they should be called mesenchymal secreting cells. Notice that he does not consider them stem cells!

MSCs secrete a large number of cytokines that reduce inflammation. It is inflammation that causes pain.

Aspirin, ibuprofen, and naproxen also reduce inflammation.

A stem cell injection with MSCs is essentially putting little aspirin factories at the site of injury.

They reduce the pain, but do little or nothing to regenerate the tissue.

For young athletes, reducing inflammation will allow the bodys healing process to work better, and thus, improve outcome.

For older patients? There is less capacity for healing.

Abstract: Worldwide, gastric cancer (GC) is one of the deadliest malignant tumors of the digestive system. Moreover, microRNAs (miRNAs) of exosomes harbored within cancer cells have been determined to induce inflammatory conditions that accelerate tumor growth and metastasis. Interestingly, the oncogenic role of bone marrow mesenchymal stem cells (BM-MSCs) in the modulation of immunosuppression, tumor invasion, and metastasis was discovered to be partly mediated through the secretion of exosomes. In this article, high expression of miRNA-221 (miR-221) in exosomes of the peripheral blood was determined to be positively correlated with the poor clinical prognosis of GC, especially with respect to tumor, node, and metastases stage. Therefore, the expression of miR-221 in exosomes of the peripheral blood may be an important detection index for GC. Proliferation, migration, invasion, and adhesion to the matrix of GC BGC-823 and SGC-7901 cells were significantly enhanced by exosomes that originated from BM-MSCs that were transfected with miR-221 mimics. In conclusion, extracted exosomes from BM-MSCs transfected with miR-221 oligonucleotides can act as high-efficiency nanocarriers, which can provide sufficient miR-221 oligonucleotides to influence the tumor microenvironment and tumor aggressiveness effectively. Notably, the use of a miR-221 inhibitor with an excellent restraining effect in exosomes provides therapeutic potential for GC in future clinical medicine.

Acupuncture

Acupuncture is a technique in which practitioners stimulate specific points on the body - most often by inserting thin needles through the skin. It is one of the most effective practices used in traditional Chinese medicine. Acupuncture stimulates nerve fibers to transmit signals to the spinal cord and brain, activating the bodys central nervous system. The spinal cord and brain then release hormones responsible for making us feel less pain while improving overall health. Acupuncture may also: increase blood circulation and body temperature, affect white blood cell activity (responsible for our immune function), reduce cholesterol and triglyceride levels, and regulate blood sugar levels.

Aquatherapy

Aquatic Physical Therapy is the practice of physical therapy in a specifically designed water pool with a therapist. The unique properties of the aquatic environment enhance interventions for patients with neurological or musculoskeletal conditions. Aquatic therapy includes a wide range of techniques allowing patients to improve their balance, muscle strength and body mechanics. Aquatic therapy works to enhance the rehabilitation process and support effectiveness of stem cell treatment.

Epidural Stimulation

Hyperbaric Oxygen Therapy

Hyperbaric Oxygen Therapy (HBOT) is the medical use of oxygen at a level higher than atmospheric pressure. The equipment required consists of pressure chamber, which may be of rigid or flexible construction, and a means of delivering 100% oxygen into the respiratory system. Published research shows that HBOT increases the lifespan of stem cells after injection and provides an oxygen-rich atmosphere for the body to function at optimum levels.

Nerve Growth Factor (NGF)

Nerve growth factor (NGF) is a member of the neurotrophic factor (neurotrophin, NTFS) family, which can prevent the death of nerve cells and has many features of typical neurotransmitter molecules. NGF plays an important role in the development and growth of nerve cells. NGF is synthesized and secreted by tissues (corneal epithelial, endothelial, and corneal stromal cells), and it can be up-taken by sympathetic or sensory nerve endings and then transported to be stored in neuronal cell bodies where it can promote the growth and differentiation of nerve cells.NGF can exert neurotrophic effects on injured nerves and promote neurogenesis (the process of generating neurons from stem cells) that is closely related to the development and functional maintenance and repair of the central nervous system. It is also capable of promoting the regeneration of injured neurons in the peripheral nervous system, improving the pathology of neurons and protecting the nerves against hypoxia (lack of oxygen)/ischemia (lack of blood supply).

Nutrition Therapy

Occupational Therapy

Occupational therapy interventions focus on adapting the environment, modifying the task and teaching the skill, in order to increase participation in and performance of daily activities, particularly those that are meaningful to the patient with physical, mental, or cognitive disorders. Our Occupational Therapists also focus much of their work on identifying and eliminating environmental barriers to independence and participation in daily activities, similar to everyday life.

Physiotherapy

Physical therapy or physiotherapy (often abbreviated to PT) is a physical medicine and rehabilitation specialty that, by using mechanical force and movements, remediates impairments and promotes mobility, function, and quality of life through examination, diagnosis, prognosis, and physical intervention. We combine our PT with stem cells for maximum physical rehabilitation improvements.

Transcranial Magnetic Stimulation

Research has shown that TMS can effectively treat symptoms of depression, anxiety, neurological pain, stroke, spinal cord injuries, autism and more. This procedure is very simple and noninvasive. During the procedure, a magnetic field generator or coil is placed near the head of the person receiving the treatment. The coil produces small electrical currents in the region of the brain just under the coil via electromagnetic induction. This electrical field causes a change in the transmembrane current of the neuron which leads to depolarization or hyperpolarization of the neuron and the firing of an action potential.

Hope is surely on the way for children with special needs as Alok Sharma, a world renowned neurosurgeon, Neuroscientist and professor, a director of NeuroGen Brain and Spine Institute India visited Nigeria recently to shed light on the efficacy of stem cells in treating children with special needs.With over 5000 patients treated from 50 countries, 68 scientific papers and 14 published books, and an overall 91% success rate, Alok was determined to enlighten participants who attended the one day seminar on stem cell awareness and its importance.According to Asok, We are the pioneers of introduction to Stem Cell Therapy for neurological disorders. We make use of holistic, comprehensive approach to treat our patients with a combination of stem cell therapy and neuro-rehabilitation. We use adult stem cells derived from the patients own bone marrow, as they are the safest and most feasible type of cells. Since every patient is different, our treatment protocol is customised according to the patients requirements.We now have a treatment that is very effective and a large number of people can benefit from this. The old thinking was that when the central nervous system is damaged then it is beyond repairs but the new thinking is that some degree of repair is possible. Stem cells have three capabilities. They repair, regenerate or replaced. It took us between seven to eight years to prove that stem cells can convert to nerve cells and when we became very sure, we went on to use on humans and the results have been outstanding He said.Asked who can be treated with the stem cell procedure and Asok says for paediatric, we treat children with autism, cerebral palsy, intellectual disability and muscular dystrophy. For adults, we treat spinal cord injury, stroke, traumatic brain injury/head injury, motor neuro disease/amyotrophic lateral scierosis and other neurological disorders.Asok explains that there are many types of stem cells used, but broadly they can be classified into 3 types:-Embryonic stem cells: Embryonic stem cells, as their name suggests, are derived from 3-4 day embryos. These are obtained from spare embryos from IVF clinics with the consent of the donor. During this early developmental period, the cells that will ultimately give rise to the developing fetus can be encouraged to develop into tissues of different origins (totipotency) contributing greatly to stem cell therapy. However, there are many ethical and medical issues regarding its use. These are therefore, not being used presently.Umbilical cord stem cells: These cells are derived from the umbilical cord which connects the baby and the mother at birth. Stem cells derived from the umbilical cord are stored by various cord blood banking companies. These stem cells do not have any major ethical issues surrounding their usage, but availability can be a problem.Adult stem cells: They can be derived from the same patient, from either the hip bone or the adipose/fat tissue. Currently, they are the most popularly used stem cells. The benefits that adult stem cells offer are:1, They are available in abundance and can be isolated easily.2, They are isolated from patients, which overcomes the problem of immunological rejection.3, Adult stem cells have the potential to replenish many specialized cells from just a few unspecialized ones.4, They do not have any ethical issues as they do not involve destruction of embryos.5, The risk of tumor formation is greatly reduced as compared to the use of embryonic stem cells.There are fears about stem cell therapy but Asok cleared the air when he said this isnt the truth as the one feared is the embryonic stem cells (ESCs) which are stem cells derived from the undifferentiated inner mass cells of a human embryo. ESCs are just one of the types of stem cells but we do not make use of that in our hospital as explained earlier, we use Adult Stem Cells. We do not use the embryotic stem cells because they have the tendency to become tumours in the body. He explained.On how the procedure works, he says a thin needle is inserted into the hip bone to pull the marrow out. The procedure takes between 15 to 30 minutes. The patient is then sent back to the room for about 3 to 4 hours to rest for the next procedureon same day, within the 2 to 4 hours, the stem cells are separated and purified in their stem cell laboratory by using density gradient centrifugation. Once the stem cells have been purified, the patient is taken back to the operation theatre and the stem cells are injected into the spinal space. In some patients, for instance, patients with muscular dystrophy, the stem cells are diluted and injected into the muscles using a very thin needle.One of the participants at the seminar, Marvis Isokpehi, whose child is autistic, had this to say I am glad I came for this seminar. Initially, we were told anything that has to do with brain damage cannot be cured or improved only managed but we see that God helping the scientist, things are getting better. My child was diagnosed by 2. She walked at 17 months, sat at 8 months and she only babbled. She could use her hands and able to put things in her mouth herself but later, the growth began to drop and along the line, I took up the challenge and went back to school to learn about taking care of her and also to help others. I went to Federal College of Education (special) Oyo and specialised in Education for the intellectually disabled. Said Marvis.For Akhere Akran, the Manager of Agatha Obiageli Aghedo Memorial Foundation and participant, one of the arms of our foundation aimed at helping to lessen the burden of the less privileged in the community is the St Agatha Children Centre, where we advocate for children with special needs. I am glad I will be going back to let the parents of these children know there is hope and I am trusting God for funds because that is truly the core of everything. I appeal to the government to fund this and encourage private organisations to help reduce the cost of this treatment to the barest minimum. Its high time we stop stigmatisation or thinking its a result of the mothers past life of the fathers mistakes. It is a medical situation that needs medical attention. Akran expressed.Andelene Thysse is a director at Stem Cell Africa and she helped facilitate the seminar and for her, it is high time Nigeria gets involved We are currently looking at establishing a stem centre at Mozambique. I would have loved that we establish in Nigeria because Nigeria is closer to everything but since we arent getting the audience required, we are going to other African countries interested. Going to NeuroGen Institute for treatment per patient costs about $11,000 imagine if Nigeria has the facility, the price can slash down to $6,000 or even below Andelene stated.Shedding more light on costing, Asok says If we are to set up such a facility in an existing hospital, the cost of setting it up is $US500, 000 and I am assuming all facilities are functioning already. If we have to set up as a whole which includes getting land and building, it will be more expensive. This may sound expensive but it is worth it because it will save you the stress for the future. More important than the money is the permission from the government of the country. The government has to give us the permission because it is what is happening in other African countries. We have had good response and cooperation from government in Kenya, South Africa and Zimbabwe. We have quite a number of Nigerians who come to us in India for this treatment. We treat 50 patients from around the world per week about 5-10 are from Africa and Nigeria is among this percentage.

Jack Massey is ready to go back to school.

Only this time, the University of Florida senior will head back to campus with his mom and a new outlook on life.

Massey suffered a spinal cord injury in a pool accident in March and is paralyzed from the chest down. After months of rehab, he's eager to get back into a familiar routine.

"It's definitely boring," the 21-year-old said at his parents' home in Niceville. "There's not a lot to do. I want to go back to school. I still have my brain. I still have everything I need to be successful."

After the accident March 17, Massey was treated at the University of Florida Shands Hospital and then was transferred to Shepherd Center, a spinal cord and brain injury rehab center in Atlanta. At Shepherd Center he met with a peer mentor, counselors and physical therapists to help him find a new normal.

Jack has remained positive throughout the past six months.

"Jack has been a fighter through all of this," said his mother, Julie. "I think he's done well. I only saw him break down once."

Before the accident, Jack was a well-rounded athlete who playing baseball and basketball and ran. He was a star on the track and field team at Niceville High School, with his 4 X 800 relay winning state his senior year.

He says the biggest challenge now is not being able to do the same things he could before.

"I can't get up and go," he said. "It didn't really start to set in until after I got out of rehab."

Jack has had to find enjoyment in other things, like reading or playing with the dogs. His friends have learned to transfer him from his wheelchair to a car so they can take him to the movies or out to eat. When they recently took a trip to the beach, Julie said five of Jack's friends carried him out to the sand a lesson on how hard it is to navigate the world in a wheelchair.

Jack said he believes technology one day will advance enough that he won't be paralyzed forever. He also volunteered to do stem cell surgery to allow doctors to study the effects of stem cells on his spine for the next 15 years. Instead of wallowing in self-pity, he's moving forward. But he'll need help.

"I'm appreciating everything in the now," he said.

Doctors have said Jack has adapted faster than expected, but there are still some everyday essential tasks that are out of his reach. He cannot write or cook. He can shower himself but can't dry himself or transfer himself in and out of his wheelchair. The Massey family hopes to secure a personal care attendant for Jack at school, but until then Julie will be in Gainesville to help him transition. An occupational therapy student from the university will also help Jack on a temporary basis.

Finding proper care for her son has proven to be a learning experience for Julie and her husband, Lance.

"I don't know how people do it," she said. "We have good health care, but then there's hidden costs. There's travel expenses. ... It's kind of humbling. Nobody should have to go to GoFundMe for medical help."

Jack wants to spend his final year as an undergrad as independent as possible. After months of helping him recover, Julie said it will be hard to let her son go. Jack is the oldest of three; his brother Lance is 19 and a student at UF and his sister Alina is 14 and attends Ruckel Middle School.

"It's like letting him go off to kindergarten again," she said.

As for life after college, Jack said he doesn't feel limited in career choices. One of his professors in the geology department encouraged him by saying that there were plenty of opportunities he could pursue in that field. Jack said he may also consider law school. One thing he's learned through this life-altering experience is that there are no limits to what he can achieve.

"I haven't done that much deep thinking. I just go with the flow," he said. "But I learned I have more perseverance. I'm more mentally tough than I thought I was. I'm appreciative for life in general. That's one of the big things."

The idea of bringing people back from the dead could one day be more than just science fiction it could be a reality. Over the past few decades, there has been progress in keeping people alive via advanced surgical techniques, organ transplants, mechanical ventilators and even saving a beating heart that has once stopped. However, when it comes to the injured brain, stem cell therapy may show promise in bringing the brain dead back to life.

In BrainCraft's video, "Ways to Bring the Brain Dead Back to Life" host Vanessa Hill explains the brain is made up of trillions of connections; our life depends on these connections. If the heart stops pumping blood for a few minutes, the brain will fall into a state of frenzy where some neurons starve to death during the blackout and others fight for life. Neurotransmitters spill out neurons in high concentrations, which leads to uncontrollable electrical changes sweeping across the brain, causing toxic chemicals to pile up and burn holes in the membranes of neurons.

All of these events lead to programmed cell death. Neurons start to die one by one, until the brain stops functioning altogether.However, scientists have started to discover the brain does have a small reservoir of stem cells that can generate new neurons.

Researchers have hypothesized whether these cells could be coaxed to turn into new neurons that self-repair the brain's injured tissue. They have also theorized the possibility of injecting neural stem cells into the brain of a patient. So, if it becomes possible to replace dead neurons, it should be possible to resurrect a person via stem cell therapy who just died.

Previous research has shown it's possible to plant stem cells in the brains of mice and help them grow into fully functioning neurons that make connections with their neighbors. In the future, these methods could be used to repair the damage done to the brain by a stroke. Currently, several trials are underway to transplant new neurons into the brains of people with Parkinson's disease.

A Philadelphia-based company, Bioquark, hopes to use stem cells to reverse death by injecting them into the spinal cords of people who have been declared clinically brain dead. The subjects will also receive an injected protein blend, electrical nerve stimulation, and laser therapy directed at the brain. The ultimate goal is to grow new neurons and spur them to connect to each other, which can potentially bring the brain back to life.

Theres the potential thata cocktail of moleculesto spurr neuronal growth could come in pill form.

This concept does raise a lot of questions, like Will we be a different person if brand new neurons connect differently? Or ,How many cells can be replaced without fully becoming a whole different person?

Stem cells are currently used for a variety of conditions, from stroke to paralysis.

But, there's currently no FDA-approved stem therapy for brain conditions. Scientists are hopeful if this approach worked on mice, it could one day work on humans too.

The Possible Ways To Bring Brain-Dead Patients Back To Life - Medical Daily

Spinal Cord Stem Cells Comments Off on The Possible Ways To Bring Brain-Dead Patients Back To Life – Medical Daily | August 25th, 2017

You might feel a bit down if you watch the news. Who wouldnt?

Angry people might be grabbing headlines and making you wonder about the future, but the antidote is all around you.

Talk to some of your neighbors. Chances are, no matter what they look like or where theyre originally from, youll find theyre actually pretty decent people just like you.

The little improvements we all try to make may not register much, but the accumulation of them all eventually does.

And if theres one tangible piece of proof that the world is changing for the better, its Lucas Lindner.

2016 was not a kind year for 22-year-old Lucas.

Last May he lost control of his pickup truck when a deer ran out on the road. The front passenger tire blew out. The truck rolled, throwing him out of the window.

When he woke up in the hospital, he was paralyzed from the neck down. He was just heading to the grocery store on a Wisconsin Sunday morning.

It was an accident that could happen to anyone, to a friend or relative.

Normally, people like Lucas have no hope of restoring motor control of their bodies ever again.

In the United States, this awful story plays out 17,000 times every year. There are a quarter of a million people in the country with paralysis.

But Lucas story is working out a little bit differently.

Lucas was airlifted to Froedtert Hospital, a teaching hospital of the Medical College of Wisconsin.

There, Dr. Shekar N. Kurpad, professor of neurosurgery, applied 15 years of research into cell transplantation for spinal cord injury.

The procedure revolutionary and so were the cells Dr. Kurpad used.

The new procedure used cells that were developed over many years by researchers at a two companies leading the way in regenerative medicine.

Researchers at these companies have discovered how to grow stem cells and make them reliable for transplantation use.

On doctor, in fact, who Ive researched extensively, has been called the father of regenerative medicine.

Ive had the pleasure of meeting with him on a number of occasions.

Whenever I am in the San Francisco Bay Area, I try to visit him to learn whats going on in the field.

And from what Ive seen the therapeutic potential is hard to understate.

And were starting to see the results in people like Lucas Lindner.

Hes still wheelchair-bound we have a lot more to learn but he now has fine motor skills in his upper body. Thats extraordinary in cases like his.

Lucass miraculous improvement is due to newly designed pluripotent stem cells They are called pluripotent because they have the power to transform into any other cell type in the body.

And this Bay Area doctors company has accumulated the technology to make that happen.

Over the next few months, well get more clinical data from patients being treated with the full 20 million-cell dose and potentially more great news of restored motor function.

The recent headlines may have been about a few angry people rioting and hating each other, but the real important news is this

Recently, when the Cincinnati Reds played the Milwaukee Brewers, Lucas threw out the opening pitch.

Many U.S. presidents and other famous people have thrown pitches, but no pitch has been as historic as this one. And the advances I highlighted today are the reason why.

As this therapy matures and gets closer to market, I believe it will make a big impact on shares of companies in this space.

Which means the right-timed move in the upcoming months means a huge potential windfall of cash for you.

More to come soon.

The pernicious effect of a heart attack includes the permanent damaging of heart muscles capacity to pump blood, causing healthy tissue to scar. People who suffer from this condition are often fatigued and cannot do as many things as they used to. They are also more prone to cardiac arrest, a condition that leads to death. Medication can help, and a heart transplant is sometimes used, though the necessity of using powerful anti-rejection drugs makes that option dangerous at the very least. The availability of donor hearts is also a limiting factor.

According to the CDC, 5.7 million Americans suffer from #Heart Failure.

Half of the people with the diagnosis die within five years. Heart failure costs the United States $30.7 billion a year in health care services, medication, and lost productivity.

A new option for people with this kind of heart failure is on the horizon, according to Mach. The idea is to grow patches of beating heart cells from a patients own tissue and then cover the parts of the heart that have been scarred by a cardiac event. The technology has the promise to allow heart failure patients to live nearly normal lives and to reduce the need for heart transplants.

Beating heart cell patches are created when blood cells are extracted from the patient and are transformed into stem cells using well known genetic engineering techniques. Then the stem cells would be used in a 3D printer to create living heart tissue, geared to match the exact size and shape of the area of the heart that has been scarred.

Then an open heart surgery procedure would be undertaken to implant the patch on the scarred tissue, including blood vessel grafts that would integrate the new tissue into the patients cardiovascular system.

The procedure would be a delicate one. The surgeon might cut the scarred tissue away and replace it with the patch or just overlay it with the theory that the scarring would go away in time. The hope is that the new tissue will beat in synchronicity with the rest of the heart.

The beauty of the procedure that even though it would cost $100,000, it will still be cheaper than a heart transplant, which costs $500,000 not including the expense of the anti-rejection drugs.

Researchers have enjoyed some success with the procedure in mice and pigs. The hope is that human trials can start in five years with the procedure being available in a clinical setting in about #Ten Years. #Stem Cell

Madalayna and Tamara Ducharme, 33 days after Madalayna received her bone marrow transplant. Photo provided by Tamara Ducharme) By Adelle LoiselleAugust 25, 2017 5:10am

Six months ago, Windsor residents came out in droves to help baby Madalayna Ducharme find a bone marrow match.

Saturday, they can help again by taking part in a bowl-a-thon dedicated to supporting the families of those who still need a transplant.

The 12th annual Bowling for Bone Marrow Bowl-a-Thon takes place Saturday at Rose Bowl Lanes on Dougall Ave. in Windsor. Check-in is at noon, and the fundraiser gets underway at 1pm.

It is the Katelyn Bedard Bone Marrow Associations biggest fundraiser of the year, and this year it can count Madalayna among its success stories.

The baby girl, who celebrated her first birthday this week, likes to dance and can stand while holding her parents fingers. Her mother, Tamara Ducharme is grateful for every day.

We were unsure if we were going to make it there, to the first birthday, she says. Were hoping that shell be a healthy little girl.

However, the struggle is not over. Friday, the family is driving up Hwy. 401 for Madalaynas six-month post-transplant appointment at Sick Kids Hospital in Toronto.

Ducharme says her daughter has bi-weekly hospital visits to ensure her medication is up to date. Madalayna still uses a feeding tube, and even months later, there is still the question whether the bone marrow transplant from her brother is working.

Theyll probably do an x-ray, says Ducharme about the upcoming appointment. Shes had a little growth. If her bones show changes that means shes on the track of getting better. Now, if there is no change, I dont know what were going to do.

Life with a young child who has received a transplant can also be very isolating, and Ducharme admits it has not been easy.

Were bubbled. We really go anywhere. We dont really play with other kids, she says. Youve gotta take the proper steps to take care of your child. If she could catch anything and it could be really detrimental.

She says the association has been very good to her family and they are grateful for their, and the communitys support over a challenging chapter in their lives.

Bryan and Joanne Bedard understand the difficulties faced by families of children waiting for a donor. They lost their three-year-old daughter, Katelyn in 2005 at the age of 3 when they were unable to find one.

Since then, they have raised money for donor clinics and awareness of the OneMatch Stem Cell and Marrow Network which now has 6,500 registered donors. The Katelyn Bedard Bone Marrow Association has also donated $115,000 to stem cell and bone marrow transplant research at both the University of Windsor and the Universite de Montreal.

Erica Honoway is scheduled to speak at the annual "Run for Mandi" charity event in Saskatoon, after her son Lincoln was saved by a bone marrow transplant.Michael Bell / Regina Leader-Post

An annual run honouring a late Canadian hockey player is working with a bone marrow and stem cell registry group in hopes of helping more people in her name.

The Run for Mandi is named for Saskatchewan hockey player Mandi Schwartz, who was diagnosed with acute myeloid leukemia in 2008 while she was part of the Yale Bulldogs hockey team. She died in 2011.

The event kicks off Sunday afternoon at River Landing. The five-kilometre run and the one-kilometre family walk will start at two, and for the first time a bone marrow and stem cell registry group will be set up at the run.

Mandis mother, Carol Schwartz, said shes proud of the work being done by the Mandi Schwartz Foundation in her daughters name.

It just makes these events more meaningful lives are being saved, Schwartz said. Theres probably no greater gift than meeting someone who got a successful match.

The OneMatch Stem Cell and Marrow Network, a part of Canadian Blood Services, will accept registrations at Sundays event. Schwartz said theyve handed out information before, but this is the first time OneMatch will swab volunteers at the event to register them in the network.

Bobbylynn Stewart with Breck Construction, the title sponsor for the event, said she has a personal stake in helping organize the run because her mother also died of acute myeloid leukemia. Its a chance for the company and the community to help other families with similar struggles, she said.

When you have a blood cancer or disorder, often times you are relying on a stem cell match through the network, Stewart said. So growing that network is vital.

Alongside the run will be a charity silent auction and a barbecue. Mandis brothers, professional hockey players Jayden and Rylan Schwartz, are also expected to attend, along with NHL players Ryan Murray and JC Lipton, and AHL player Brandon Gormley.

Erica Honoway, scheduled to speak before the run, said she is haunted by how close her family came to sharing in the Schwartzs tragedy.

Her son Lincoln was diagnosed with aplastic anemia last year, but a bone marrow transplant helped save his life.

In all the registries in the world, they found two matches for Lincoln, Honoway said. Every single person who gets on is another chance for someone to have their life saved.

Bacterial infection activates hematopoietic stem cells in the bone marrow and significantly reduces the ability to produce blood through induced proliferation. Credit: Professor Hitoshi Takizawa

It has been thought that only immune cells would act as the line of defense during bacterial infection. However, recent research has revealed that hematopoietic stem cells, cells that create all other blood cells throughout an individual's lifetime, are also able to respond to the infection. A collaboration between researchers from Japan and Switzerland found that bacterial infection activates hematopoietic stem cells in the bone marrow and significantly reduces their ability to produce blood by forcibly inducing proliferation. These findings indicate that bacterial infections might trigger dysregulation of blood formation, such as that found in anemia or leukemia. This information is important to consider in the development of prevention methods for blood diseases.

Background: Bacterial Infection and the Associated Immune Reaction

When a person becomes infected with a virus or bacteria, immune cells in the blood or lymph react to the infection. Some of these immune cells use "sensors" on their surfaces, called Toll-like receptors (TLR), to distinguish invading pathogens from molecules that are expressed by the host. By doing so, they can attack and ultimately destroy pathogens thereby protecting the body without attacking host cells.

Bone marrow contains hematopoietic stem cells which create blood cells, such as lymphocytes and erythrocytes, throughout life. When infection occurs, a large number of immune cells are activated and consumed. It therefore becomes necessary to replenish these immune cells by increasing blood production in bone marrow. Recent studies have revealed that immune cells are not the only cells that detect the danger signals associated with infection. Hematopoietic stem cells also identify these signals and use them to adjust blood production. However, little was known about how hematopoietic stem cells respond to bacterial infection or how it affected their function.

Proof: Hematopoietic Stem Cell Response to Bacterial Infection

Researchers from Kumamoto University and the University of Zurich analyzed the role of TLRs in hematopoietic stem cells upon bacterial infection, given that both immune cells and hematopoietic stem cells have TLRs. Lipopolysaccharide (LPS), one of the key molecules found in the outer membrane of gram negative bacteria and known to cause sepsis, was given to laboratory animals to generate a bacterial infection model. Furthermore, researchers analyzed the detailed role of TLRs in hematopoietic stem cell regulation by combining genetically modified animals that do not have TLR and related molecules, or agents that inhibit these molecules.

The results showed that LPSs spread throughout the body with some eventually reaching the bone marrow. This stimulated the TLR of the hematopoietic stem cells and induced them to proliferate. They also discovered that while the stimulus promoted proliferation, it also induced stress on the stem cells at the same time. In other words, although hematopoietic stem cells proliferate temporarily upon TLR stimulation, their ability to successfully self-replicate decreases, resulting in diminished blood production. Similar results were obtained after infection with E. coli bacteria.

Future Work

This study reveals that hematopoietic stem cells, while not in charge of immune reactions, are able to respond to bacterial infections resulting in a reduced ability to produce blood. This suggests that cell division of hematopoietic stem cells forced by bacterial infection induces stress and may further cause dysregulated hematopoiesis like that which occurs in anemia or leukemia. "Fortunately we were able to confirm that this molecular reaction can be inhibited by drugs," said one of the study leaders, Professor Hitoshi Takizawa of Kumamoto University's IRCMS. "The medication maintains the production of blood and immune cells without weakening the immune reaction against pathogenic bacteria. It might be possible to simultaneously prevent blood diseases and many bacterial infections in the future."

The parents of a Saskatchewan-born Yale University hockey player are trying to connect more people with a bone marrow and stem cell network that could save lives.

Rick and Carol Schwartz will be in Saskatoon on Sunday for the sixth annual Run for Mandi named after their daughter Mandi Schwartz, who was diagnosed with acute myeloid leukemia in December 2008 and died in April 2011.

Officials from the OneMatch Stem Cell and Marrow Network, part of Canadian Blood Services, will take swabs from volunteers in hopes of connecting donors with patients who need stem cell transplants.

Its the first time the event will have on-site registration for the network.

Fewer than 25 per cent of people find a stem cell donor in their family and only 50 per cent find a match in the international network of donors, according to Blood Services.

Mandi never found one.

It was frustrating to know that. Its almost like we let her down, Rick Schwartz said.

In 2010, his daughter penned a letter, stating her hope that doctors would find her a life-saving match. She also hoped to increase the donor registry to help others.

If someone else in Mandis family needed a stem cell transplant, she wouldve been the first person to help out, her mother said.

I just know she would be front and centre in leading a drive if she were with us today, Carol Schwartz said.

Another registration drive in Mandis name happens annually at Yale University. So far, more than 6,000 people have registered and 37 have resulted in stem cell matches.

Ideal candidates are between the ages of 17 and 35 and meet certain health criteria.

If a person registers and matches with a person in need, its usually as easy taking blood, according to Run for Mandi co-organizer Bobbylynn Stewart.

Fifteen per cent of the time, they do require your bone marrow, said Stewart, who lost her mother to acute myeloid leukemia.

They go in through your hip and draw it through there, so its under anesthesia. Its about an hour-long process.

Sundays event lasts from 1 p.m. to 4 p.m. and running isnt required.

Lincoln Honoway, who was three when he was admitted to Regina General Hospital last year with dangerously low blood counts, will be in attendance.

After finding a stem cell transplant, Lincolns blood cell counts have started to rise and stabilize.

The run is planned for River Landing, with pro hockey players Ryan Murray, JC Lipon and Brandon Gormley expected to be there.

Mandis brother, Jaden Schwartz of the St. Louis Blues, will attend as well.
