Core Insights - A breakthrough in medical 3D printing has been achieved by a research team from the California Institute of Technology, developing a technology that allows for the in-situ creation of medical implants and customized therapeutic tissues without traditional invasive surgery [1][2] - The new technique, named "Imaging-Guided In-Situ Ultrasound Printing" (DISP), combines focused ultrasound with specially designed "ultrasound ink" to precisely manufacture biomaterials deep within the body, potentially transforming personalized medicine [1][2] Group 1 - The DISP technology utilizes focused ultrasound to trigger a gelation reaction of biological ink, enabling in-situ printing at targeted locations within the body [1] - The "ultrasound ink" consists of biopolymers, imaging contrast agents, and temperature-sensitive liposomes, which can be delivered to deep tissues via injection or catheter [1][2] - An automated ultrasound transducer operates according to a pre-set digital model, generating localized micro-heating to release cross-linking agents, leading to rapid gelation of the ink [1][2] Group 2 - The biological ink used in this technology is highly tunable, allowing for the design of properties such as enhanced conductivity, drug release, tissue adhesion, and even real-time imaging capabilities [2] - Successful experiments demonstrated the printing of drug-loaded functional biomaterials near bladder tumors in mice and in deep muscle tissues of rabbits, showcasing DISP's potential in drug delivery, tissue repair, and bioelectronic device construction [2] - Safety assessments indicated that the technology did not cause significant inflammation or tissue damage, and the gel ink is not naturally cleared by the body within a week, indicating good biocompatibility [2] Group 3 - The biomedical field is a significant application area for 3D printing technology, traditionally involving external printing of patient-matched scaffolds before surgical implantation [2] - The DISP technology addresses the limitations of traditional methods by enabling direct in-body printing of biomaterials, potentially alleviating patient discomfort associated with surgeries [2] - Future advancements, including the integration of artificial intelligence for real-time path planning, may revolutionize the traditional model of constructing and implanting 3D printed biomaterials, further advancing personalized medicine [2]

Group 1 - A new study published in the journal "Cell" highlights the use of generative artificial intelligence (AI) to design synthetic DNA sequences that act as "gene switches" to control gene expression in specific mammalian cells, marking a milestone in synthetic biology [1][2] - The AI model was trained to predict suitable combinations of DNA letters (A, T, C, G) to create DNA fragments that do not exist in nature, allowing for tailored gene expression patterns in specific cell types, such as enabling stem cells to develop into red blood cells instead of platelets [1][2] - The research team conducted over 64,000 experiments over five years to build the largest synthetic enhancer database for blood cells, testing 38 different transcription factor binding site arrangements and tracking enhancer activity across seven stages of blood cell development [2] Group 2 - The ability to create artificial enhancers that function as precise "on/off" switches in specific cells significantly reduces side effects on healthy cells, which is crucial for the development of next-generation gene therapies [2] - The study revealed interesting phenomena, such as some enhancer combinations exhibiting "negative synergistic effects," where two factors that individually promote gene expression can inhibit activity when combined, providing new insights into gene regulation [2][3] - This advancement opens new avenues for personalized medicine and precision gene therapy in the future [3]
