Regenerative Medicine Using Living Cell Tubes

Posted by in categories: bioprinting, biotech/medical, life extension

😀 They say we could even regenerate human limbs this way aswell as repair human blood vessels.


Cell tubes, made entirely from a patient’s own cells, are just as elastic as blood vessels but much stronger. Skin cells cultured into lumps are skewered on needles on a base, similar to a Kenzan, a tool used in Japanese flower arrangements, and formed into a tube. The technique, called the Kenzan Method, was made possible by a 3D bioprinter. A clinical trial is underway in Japan to transplant these tubes into humans in place of blood vessels. Studies are being done to apply them to nerves and organs.

Scientists 3D-Print Hair Follicles in Lab-Grown Skin

The technique represents an important step in engineering skin grafts, drug testing. A team led by scientists at Rensselaer Polytechnic Institute has 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in skin healing and function.

The finding, published in the journal Science Advances, has potential applications in regenerative medicine and drug testing, though engineering skin grafts that grow hair are still several years away.

“Our work is a proof-of-concept that hair follicle structures can be created in a highly precise, reproducible way using 3D-bioprinting. This kind of automated process is needed to make future biomanufacturing of skin possible,” said Pankaj Karande, Ph.D., an associate professor of chemical and biological engineering and a member of Rensselaer’s Shirley Ann Jackson, Ph.D. Center for Biotechnology and Interdisciplinary Studies, who led the study.

New 3D-printed tumor model enables faster, less expensive and less painful cancer treatment

Posted by in categories: bioprinting, biotech/medical, computing, mathematics

An international team of interdisciplinary researchers has successfully created a method for better 3D modeling of complex cancers. The University of Waterloo-based team combined cutting-edge bioprinting techniques with synthetic structures or microfluidic chips. The method will help lab researchers more accurately understand heterogeneous tumors: tumors with more than one kind of cancer cell, often dispersed in unpredictable patterns.

The research, “Controlled tumor heterogeneity in a co-culture system by 3D bio-printed tumor-on-chip model,” appears in Scientific Reports.

Traditionally, would biopsy a patient’s tumor, extract cells, and then grow them in flat petri dishes in a lab. “For 50 years, this was how biologists understood tumors,” said Nafiseh Moghimi, an post-doctoral researcher and the lead author of the study. “But a decade ago, repeated treatment failures in made scientists realize that a 2D model does not capture the real tumor structure inside the body.”

Creating Sapient Technology and Cyborg Rights Should Happen Soon

Posted by in categories: 3D printing, bioengineering, bioprinting, biotech/medical, cyborgs, existential risks, genetics, robotics/AI, transhumanism

Here’s my latest Opinion piece just out for Newsweek…focusing on cyborg rights.


Over the past half-century, the microprocessor’s capacity has doubled approximately every 18–24 months, and some experts predict that by 2030, machine intelligence could surpass human capabilities. The question then arises: When machines reach human-level intelligence, should they be granted protection and rights? Will they desire and perhaps even demand such rights?

Beyond advancements in microprocessors, we’re witnessing breakthroughs in genetic editing, stem cells, and 3D bioprinting, all which also hold the potential to help create cyborg entities displaying consciousness and intelligence. Notably, Yale University’s experiments stimulating dead pig brains have ignited debates in the animal rights realm, raising questions about the ethical implications of reviving consciousness.

Cutting Edge Levitation Technologies Aim to Revolutionize Bioprinting and Space Travel

Posted by in categories: bioprinting, biotech/medical, space travel

A new project is using cutting-edge levitation techniques to make bioprinting heart models and other complex tissues a reality.

Dubbed PULSE, the project combines the recently developed techniques of acoustic levitation and magnetic levitation to manipulate individual components without actually touching them. It’s a process that the researchers involved hope will one day facilitate the bioprinting of organs and other human tissues in much greater detail and complexity than what is achievable with current techniques.

If perfected, the researchers also hope this type of bioprinting could even help on long-term space missions as more accurate organ models can create more accurate defenses against radiation and other stresses of space travel.

Standard immunotherapy procedures also employ intravenous injections loaded with NK cells to treat cancer but several limitations with this approach prevent it from delivering satisfying results. For instance, many NK cells lose their viability during the therapy and often fail to target the tumors, according to the researchers.

Bioprinting personalized tissues and organs within the body: A breakthrough in regenerative medicine

Posted by in categories: 3D printing, bioprinting, biotech/medical, chemistry, cyborgs, life extension

In situ bioprinting, which involves 3D printing biocompatible structures and tissues directly within the body, has seen steady progress over the past few years. In a recent study, a team of researchers developed a handheld bioprinter that addresses key limitations of previous designs, i.e., the ability to print multiple materials and control the physicochemical properties of printed tissues. This device will pave the way for a wide variety of applications in regenerative medicine, drug development and testing, and custom orthotics and prosthetics.

The emergence of has resulted in substantial improvements in the lives of patients worldwide through the replacement, repair, or regeneration of damaged tissues and organs. It is a promising solution to challenges such as the lack of organ donors or transplantation-associated risks. One of the major advancements in regenerative medicine is on-site (or “in situ”) bioprinting, an extension of 3D , which is used to directly synthesize tissues and organs within the human body. It shows great potential in facilitating the repair and regeneration of defective tissues and organs.

Although significant progress has been made in this field, currently used in situ bioprinting technologies are not devoid of limitations. For instance, certain devices are only compatible with specific types of bioink, while others can only create small patches of tissue at a time. Moreover, their designs are usually complex, making them unaffordable and restricting their applications.
