An Embryonic Sac At 6 Weeks 1 Day Is That Bad
I'm 6 wks pregnant. Having spotting for 4 days. Done ultrasound 4 days ago. The result is collapse sac and no embryonic. Am I candidate?
Can't answer this:
As phrased. Candidate for what?
You really need to ask the person who ordered the study what these findings mean and what are your options. Good luck! ...Read more
It's consider normal a gestational sac of 5.5mm at 5 weeks + 1day with yolk sac and incipient embryonic pole?
Yes: I think you are asking if it is normal at 5 weeks to only see a yolk sac located in the gestational sac. If so then yes that is what is expected. A fetal pole can be seen after the 6th week. ...Read more
At an ultrasound OB said there was some blood inside the embryonic sac but baby was still growing it should be ok. 10weeks what could happen? Causes?
Yes, see below: Embryonal carcinoma is a rare but aggressive testicular tumor. It may be in the pure form or with mixed germ cell component, including yolk sac tumor when it has elevated AFP level. It can invade the surrounding lining of the testicle, invade the spermatic cord, spread to the regional lymph nodes, spread to other lymph nodes, to the lungs or other organs. ...Read more
Can spread: Can spread to any part of the body including the brain ; need full body scan to eval. ...Read more
I'm on 6wks and 4days of pregnancy. Having spotting/bleeding. Done with ultrasound 5days ago, the result is collapse sac and no embryonic. Mean?
Doctor visit: In a normal pregnancy one expects to see a fetal pole with a heart beat by 6-7 weeks gestation. If your sonogram shows a collapsed sac then this may indicate the pregnancy is not progressing normally. It will be important to have your doctor evaluate you and determine if a miscarriage has occurred. ...Read more
At 5w+5d gestational sac 11.5mm, yolk sac 4mm, embryonic pole not measured but visible. Not heart beat detected. It's ok?

A this poitnt: Human embryonic stem cells are being studied to define stem cell biology and in animal models to look at tissue and organ repair. This would be considered preclincial at this point, whcih is to say he's are not being used to treat human disease. ...Read more
Origin: Embryonic stem cells are derived from fertilized eggs created to help couples who have difficulty conceiving. This is "murder" according to some religionists. Other stem cells come from other sources. However, since the striking success of embryonic stem cells in early studies on wet macular degeneration, even the conservative presidential candidate no longer seems opposed to their use. ...Read more
Rare tumor: A very malignant tumor of the liver that appears in younger people. In contrast to the more common tumor, the hepatocellular tumor or hepatoma, the embryonal sarcoma is a primitive mesenchymal tumour of unknown aetiology associated with multiple genetic mutations. Also known as malignant mesenchymoma, mesenchymal sarcoma, primary sarcoma, undifferentiated sarcoma, surgical resection needed. ...Read more
Stem cells: There are three classes of stem cells: totipotent, multipotent, and pluripotent. Multipotent stem cells (umbilical cord stem cells) can give rise to a small number of different cell types. Pluripotent stem cells (embryonic stem cells) can give rise to any type of cell in the body except those needed to develop a fetus. A fertilized egg is considered totipotent, meaning that its potential is total. ...Read more
Perhaps our future.: A human embryo consists of 50-150 embryonic stem cells 4–5 days after fertilization, and those few cells eventually differentiate into all of the different specialized cells that compose the entire human body. Since those stem cells can potentially be anything they want to be, the potential for curing multitudes of human disease, using them, is enormous. ...Read more
Good question!: As I understand it, the right-wing groups calling themselves "pro-life", have consistently opposed use of embryonic stem cells from abortuses or stored fertilized eggs from ivf and family planning centers, as an extrapolation of their stance on many issues that touch upon the definition of life. ...Read more
Yes: Controversy surrounds how these embryonic stem cells obtained... From living or dead donors (fetus), will growing fetuses become a big market for stem cell supplies? This is a big problem if they are not your own stem cells harvested when you were born. Some people use cord stem cells, however the risk of any genetic material good/bad (ie. Cancer, disorders) can be transmitted. ...Read more

Induced Pluripotent: Another type of stem cells is called induced pluripotent stem cells, or ips. These are adult stem cells that have been genetically altered to be more like embryonic stem cells. You can read more about the difference between the three types of stem cells at my blog here: http://www. Cosmeticsurg. Net/blog/2011/09/16/stem-cell-types/. ...Read more
In research now: Use of adult mesenchymal stem-stromal cells (mscs) are currently in clinical trial in us/internationally. Trend is toward use of fat derived mscs, havested by liposuction, isolated and concentrated in tissue culture. Early reports suggest significant improvement in neurological, autoimmune and organ functions. Many more mscs in fat than bone marrow making ad-msc the center of most research now. ...Read more
