Cytori demonstrates adipose stem cells improve cardiac function in preclinical heart attack model

17.10.2005


First preclinical report of autologous stem cells harvested and administered the day of heart attack



Cytori Therapeutics, Inc. (Frankfurt: XMP), today presented results demonstrating that adipose stem cells improved cardiac function following a severe heart attack in a porcine study. This is the first preclinical study in which the injected cells were autologous, meaning they came from the animals’ own tissue, were not cultured, so that they did not undergo multiple cell divisions to achieve a target dose of cells, and were harvested and administered on the day of the heart attack. The results of the study, conducted in collaboration with Tulane University, were presented at the 17th annual Transcatheter Cardiovascular Therapeutics 2005 conference in Washington, D.C. (abstract no. 158).

In this randomized study, 17 animals received either injections of their own adipose stem and regenerative cells (treated) or a saline injection (control) via catheter into the artery at the site of the heart attack. After eight weeks, there was a statistically significant reduction in the perfusion defect, which is the area of the heart deprived of oxygen as a result of the infarct. A corresponding benefit was observed by the improvement in ejection fraction, a common measure of the heart’s pumping efficiency.


"Our study was unique in that the animals received an injection of autologous cells that were not cultured and administered immediately following a heart attack," said Marc H. Hedrick, M.D., President for Cytori Therapeutics. "Additionally, it shows that a sufficient number of cells could be accessed from adipose tissue in real-time to achieve a therapeutic effect, which closely approximates a clinical setting where timely delivery may be critical. These data confirm our previous results and will serve as an important component of our forthcoming application to initiate European clinical studies next year."

Adipose tissue, also known as fat, is an abundant source of stem cells and other regenerative cells that can contribute to the repair and healing of damaged tissue. These cells have been shown to reduce the extent of a heart attack and promote restoration of heart function by a variety of mechanisms, including promotion of blood vessel growth, and differentiate into cardiac muscle tissue.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
