1. Explain how cells specialize to form specific tissue and organs.
Cells specialize through birth when the embryonic stem cells take in different proteins that make them either be epithelial, muscle, connective, or nervous tissue. For example, stem cells can take in specific proteins to become epithelial tissue which protects the body’s surface, lines the internal organs, and composes the glands. The Eritrean man needed a new wind pipe that was constructed by cells that specialize in creating connective tissue that is meant to support the throat for the digestive system.
2. Explain what is already being accomplished in the areas of tissue and organ bioengineering and what still remains to be accomplished.
We have been able to recreate and grow tissues and cells, but have had complications with creating full organs such as kidney’s, hearts, and lungs. For example, the windpipe is an easy creation to make, but if someone needed a complicated organ such as a heart we haven’t reached the level of expertise to do that. We have been able to create various samples of epithelial tissue for skin grafting with burn victims, create small pieces of muscle tissue for victims of lost pieces of limbs as well. With the creation of full larger organs still needing to be accomplished, I would say bioengineering has gone quite a ways for now.
3. Discuss how these medical advancements impact individuals and society.
These medical advancements allow people who have gone through accidents and endangerments to continue their lives without error by bringing more organs that can help them function more in life. They also allow for society’s standards of what is normal to fade away, opening people’s minds to new possibilities. These medical advancements have also angered various other people thinking that these practices are wrong and shameful, causing a lot of controversy for the subject of bioengineering. These individuals who are in need of a donor organ that will wait for months at a time can now get an organ that doesn’t have the chance of being rejected quicker into their body.

Biotechnology, Stem Cell replacement. Stem cell replacement is a huge goal for scientist it will also have a huge positive impact on society, reason being this technology would allow doctors to create any tissue or organ in the body from a single stem cell. This would change everything in a positive way. This would allow them to create major organs, tissues they may even be able to cure certain diseases. This may lead to one of the greatest success in the history of science.…

Scientists are currently working on trying to print human organs on 3D printers. This process is called bioprinting and “it uses an “ink” of stem cells to produce 3D shapes that can be places into the human body, where hopefully the cells will be accepted by the existing tissues.” Also, artificial limbs are being created with 3D printers. A boy lost both of his arms to a bombing in Sudan, and now is able to use an artificial arm to change his life. Scientists are also printing body parts ranging from plastic skulls to artificial eyes.…

At first glance, the very idea of tissue engineering seems absurd. How could an organ engineered in a lab possibly function properly in such a complex environment as a human body? These doubts can be proven wrong by simply looking at the striking progress that has been made in the field. Scientist at Brown have successfully cultured cells to engineer matrices to grow organ tissue on. In combination with a matrix, tissue engineering can be used to create organs in the lab. Tissue engineer Nina Tandon claims that scientist have been able to utilize induced…

Stem cells are used a lot in regenerative medicine. The stem cells are what are used to create the organ in the lab. The scientists first take the stem cells and place them and a model for them to grow on. Once the stem cells have grown and formed tissues around the mold they add what the organ needs to do its function. They then send electrical signals to bring the organ to life, like a heartbeat, almost as if they are reviving it. This has the potential of saving millions of lives in the long run, maybe even billions, or eventually trillions if mankind last that long. Of course technology will advance and there will be different techniques and approaches for regenerative medicine, but technology is developing faster than ever in the past 100 years, so we may not be as far away from achieving great things as you might think. Say someone needs a new bladder, but no bladders that match them are currently available. Well with regenerative medicine we can create a new bladder in a hopefully short period of time with the tissues and cells of the person who needs the bladder. Therefor there will be no shortage of organs…

There is no evidence of a specific inventor of biomedical engineering, however, it’s earliest form of evidence, was first recoded from a mummy from Thebes. The preserved body has the first known signs of prosthesis in the form of a wooden toe that was attached to the foot using string. This proves that the continuous development of biomedical engineering is enabled by the natural human instinct to improve and increase the ease of mobility and improve life. The field of biomedical engineering really began to emerge after WWII. By utilizing modern technology, bioengineers have found more effective ways of applying the principles of biomedical engineering. The search to improve the quality of human life has always been present; however the methods and products produced in this field in modern day society with the use of modern sciences have been constantly improving on the effective solutions for health issues since the earlier attempts before them.…

First, they are unspecialized cells capable of renewing themselves through cell division after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions (Stem Cell Information).…

The advancement in technology has lead to the treatment of many diseases. Stem cell research has provided hope and has brought optimism among the scientists and doctors in curing the patients who suffered or died due to the once called "untreatable" diseases decades ago. Stem cells are the ones which can develop into any type of a body cell including the cells of blood, liver, brain, muscles, and many more. They are found in adult bone marrow, embryos, fetuses, and blood from the umbilical cord (Bailey 100). Stem cell research is the latest advancement in biotechnology which shows how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. This technique has lead scientists to research about the possibility of cell-based therapies to treat disease, which is often referred to as regenerative or reparative medicine.…

Generally, progress is the process of improving over time, but as it relates to science, progress is the idea that science increases its problem-solving ability through the application of some scientific method. Overtime, science has indeed made tremendous progress through various analytical methods; one of the most controversial beings, ‘bioengineering’. Bioengineering is believed to be merely cloning, but bioengineering is specifically the application of sciences and engineering techniques that solve problems such as replacement of body parts, detection of diseases, and cloning. In recent years, there have been several cases where lives were saved due to the replacement of a dysfunctional body part. Early detection of diseases has also increased dramatically with the help of modern technology. I adamantly believe that bioengineering is extremely beneficial to the progress of our society, species, and/or culture, but like everything else in life it has a negative effect.…
