A team of bioengineers at Houston's own Rice University have created an implant that can produce insulin for Type 1 diabetics. The device is being created by using 3D printing and smart biomaterials.

Omid Veiseh, an assistant professor of bioengineering, and Jordan Miller, associate professor of bioengineering, have been working on the project for three years and have received support from JDRF by way of a grant. Veiseh has a decade of experience developing biomaterials that protect implanted cell therapies from the immune system an Miller has spent more than 15 years specializing in 3D print tissues with vasculature, or networks of blood vessels.

"If we really want to recapitulate what the pancreas normally does, we need vasculature," Veiseh says in a news release. "And that's the purpose of this grant with JDRF. The pancreas naturally has all these blood vessels, and cells are organized in particular ways in the pancreas. Jordan and I want to print in the same orientation that exists in nature."

The challenge with Type 1 diabetes is balancing insulin intake, and studies estimate that less than a third of Type 1 diabetics in the U.S. are able to achieve target blood glucose levels consistently. Veiseh and Miller are working toward demonstrating that their implants can properly regulate blood glucose levels of diabetic mice for at least six months. To do that, they'll need to give their engineered beta cells the ability to respond to rapid changes in blood sugar levels.

"We must get implanted cells in close proximity to the bloodstream so beta cells can sense and respond quickly to changes in blood glucose," Miller says, adding that the insulin-producing cells should be no more than 100 microns from a blood vessel. "We're using a combination of pre-vascularization through advanced 3D bioprinting and host-mediated vascular remodeling to give each implant several shots at host integration."

Another challenge these experts are facing is a potential delay that can happen if the implant is too slow to respond to high or low blood sugar levels.

"Addressing that delay is a huge problem in this field," Veiseh says. "When you give the mouse — and ultimately a human — a glucose challenge that mimics eating a meal, how long does it take that information to reach our cells, and how quickly does the insulin come out?"

By incorporating blood vessels in their implant, he and Miller hope to allow their beta-cell tissues to behave in a way that more closely mimics the natural behavior of the pancreas.

Houston expert: New technologies are improving lives of those living with type 1 diabetes

Guest column

Type 1 diabetes (T1D) is an autoimmune disease where insulin-producing beta cells in the pancreas are mistakenly destroyed by the body's immune system. Insulin is vital in controlling blood-sugar or glucose levels. Not only do you need proper blood-sugar levels for day-to-day energy, but when blood-sugar levels get too high (hyperglycemia) or too low (hypoglycemia), it can cause serious problems and even death. Because of this, those with T1D are dependent on injections or pumps to survive.

The causes of T1D are not fully known, and there is currently no cure; however, advancing technologies are making it easier to live with T1D.

Monitoring

Those who have had T1D for decades might recall having to pee into a vial and test reagent strips in order to check their blood-sugar levels. Thankfully, this evolved into glucometers, or glucose meters. With a glucometer, those with T1D prick their finger and place a drop on the edge of the test strip, which is connected to the monitor that displays their results. Nowadays, glucometers, much like most T1D tech, can be Bluetooth enabled and sync with a smartphone.

From there, scientists have developed the continuous glucose monitor (CGM) so that those with T1D can monitor their blood sugar 24/7. All you need to do is insert a small sensor under the skin. The sensor then measures glucose levels every few minutes, and that information can then be transmitted to smartphones, computers and even smart watches.

Monitoring blood-sugar levels is vital for those with T1D, particularly because it helps them stay more aware of their body, know what to do and even what to expect, but they also have to actively control those levels by injecting insulin. Think of a monitor as the "check engine" light. It can tell you that there may be a problem, but it won't fix it for you. To fix it, you would need an injection or a pump.

Pumps and artificial pancreas

The development of insulin pumps has made a huge impact on the lives of those with T1D and parents of children with T1D by making it easier to manage their blood-sugar levels. 50 years ago, the prototype of the insulin pump was so large, it had to be a backpack, but with today's technology, it is about the size of a smartphone. The pump is worn on the outside of the body, and it delivers insulin through a tube which is placed under the skin. Insulin pumps mimic the way a pancreas works by sending out small doses of insulin that are short acting. A pump can also be manipulated depending on each person's needs. For example, you can press a button to deliver a dose with meals and snacks, you can remove it or reduce it when active and it can be programmed to deliver more at certain times or suspend delivery if necessary.

One of the most recent and trending developments in T1D research is the artificial pancreas, or more formally referred to as the automated insulin delivery (AID) systems. Essentially, the artificial pancreas is an insulin pump that works with a CGM. The CGM notifies the insulin pump of your blood-sugar reading, which acts accordingly to restore your blood sugar to the target level. The artificial pancreas allows those with T1D to be even more hands off, as it does essentially everything: It continuously monitors blood-sugar levels, calculates how much insulin you would need, which can be done through smart devices, and automatically delivers insulin through the pump.

Living with T1D is a 24/7/365 battle; however, the advances in technology make it easier and safer to live with the disease. Organizations like JDRF play a huge role in investing in research, advocating for government support and more.

November was National Diabetes Awareness Month, and this year is particularly special for JDRF, as it is the 50th year of the organization. JDRF was founded in 1970 by two moms. The community grew to include scientists, lobbyists, celebrities and children—all determined to improve lives and find cures.

Bound by a will stronger than the disease, this year during National Diabetes Awareness Month (NDAM), JDRF celebrates "The Power of Us." We are reflecting on the power of our community and reminding ourselves and the public of how far we've come in the fight against T1D.

Houston femtech co. debuts first holistic wellness suite following rebrand

work perks

Houston-based femtech company Work&, previously Work&Mother, debuted new lactation suites and its first employee wellness space at MetroNational’s Memorial City Plazas this month.

The 1,457-square-foot Work& space features three lactation rooms and five wellness suites, the latter of which are intended to offer employees a private space and time for telehealth appointments, meditation, prayer, and other needs. The hybrid space, designed by Houston-based Inventure, represents Work&'s shift to offer an array of holistic health and wellness solutions to landlords for tenants.

Work& rebranded from Work&Mother earlier this year. The company was previously focused on outfitting commercial buildings with lactation accommodations for working parents, equipped with a hospital-grade pump, milk storage bags, sanitizing wipes, and other supplies. While Work& will still offer these services through its Work&Mother branch, the addition of its Work&Wellbeing arm allows the company to also "address the broader wellness needs of all employees," according to an announcement made on LinkedIn.

"We are thrilled to bring Work&Mother and Work&Wellbeing to The Plazas," Jules Lairson, co-founder and COO of Work&, said in a news release. “This partnership brings every stakeholder together – employees, employers and landlords all benefit from this kind of forward-thinking tenant experience. We are excited to launch our Work&Wellbeing concept with MetroNational to ensure that all employees have their wellness needs met with private, clean, quiet spaces for use during the workday.”

The new space is available to all tenants across Memorial City Plazas, comprised of three office towers totaling 1 million square feet of Class A office space. In addition to the lactation and wellness suites, the space also features custom banquettes, private lounge seating and phone booths.

“As a family-owned and operated company, MetroNational is deeply committed to fostering a workplace that supports both productivity and the well-being of all our tenants,” Anne Marie Ratliff, vice president of asset management for MetroNational, added in the release. “Partnering with Work& reinforces this commitment, enhancing our workplace experience and setting a new standard for tenant amenities.”

Work& has five Houston locations and several others in major metros, including New York, Austin, D.C., Boston, Chicago, San Francisco, and Miami. According to its website, the company will also introduce a Work&Wellbeing suite in New York.
