LONDON Greg Olsen Panthers Jersey , Sept. 20 (Xinhua) -- For the first time researchers have used genome editing techniques to study gene function in human embryos, revealing the role of a key gene in the embryos' first few days of development, according to a study released on Wednesday by the Francis Crick Institute.
The results could help scientists better understand the biology of human early development.
The team led by researchers from the institute used genome editing techniques to stop a key gene from producing a protein called OCT4, which normally becomes active in the first few days of human embryo development.
After the egg is fertilized, it divides until at about seven days it forms a ball of around 200 cells called the "blastocyst." The study found that human embryos need OCT4 to correctly form a blastocyst.
"If we knew the key genes that embryos need to develop successfully, we could improve IVF treatments and understand some causes of pregnancy failure Kawann Short Panthers Jersey ," said Dr Kathy Niakan from the Francis Crick Institute, who led the research, "It may take many years to achieve such an understanding; our study is just the first step."
As well as human embryo development, OCT4 is also thought to be important in stem cell biology. Pluripotent stem cells can become any other type of cell, and they can be derived from embryos or created from adult cells such as skin cells. Human embryonic stem cells are taken from a part of the developing embryo that has high levels of OCT4.
"We have the technology to create and use pluripotent stem cells, which is undoubtedly a fantastic achievement Trai Turner Panthers Jersey , but we still don't understand exactly how these cells work," said Dr James Turner, co-author of the study from the Francis Crick Institute.
The study has been published in the journal Nature.

Although some couples stick to an “mutual pleasure exclusive” arrangement,
many others like to expand their boundaries beyond penetrative male organ-female
organ coupling – and for these couples, oral sensual activity is an obvious
alternative. There’s nothing wrong with traditional oral activity by any
means Ryan Kalil
Panthers Jersey , but the more playful couples may wish to add a
dollop of extra fun to their proceedings, and so may be interested in what oral
sensual games they can play to make the experience even more engaging. As long
as a man’s member health or a woman’s female organ health isn’t called into
question, jumping into oral sensual games can be part of a good, healthy
relationship.
Simply by using their imagination, couples can come up with
oral sensual games of their own devising. However, to jump-start the
process Luke Kuechly
Panthers Jersey , the following are a few games they may wish to
add to the experience.
Oral sensual activity dice
There are
countless variations using dice to direct oral sensual activities. Perhaps the
most basic is for one partner to roll the dice. The number of the dice
determines the length of time they administer orally to their partner. For
example, depending upon what method of measurement has been agreed upon, a woman
who rolls a seven might give her man’s member seven licks or pleasure him for
seven minutes.
But there can be other variations. For example, have the
two dice stand for different things. One dice stands for, say, the number of
minutes an oral activity must be performed. For the other dice Cam Newton
Panthers Jersey , each number has a different meaning, such
as:
• One – traditional oral sensual activity
• Two – oral sensual
activity with an ice cube in the mouth
• Three – focusing solely on the sacks
(for the man) or the chest (for the woman)
• Four – oral sensual activity
while humming
• Five – both partners perform orally on each other
simultaneously
• Six – roller’s choice – whatever he or she wants to do
orally
Guided by a game show
Pick a televised game show,
preferably one with only two competitors or two teams. The man chooses one
contestantteam, the woman the other. When one person’s contestant or team is up,
they are receiving oral sensual activity from the other, and vice versa. If
their choices compete against each other at the same time Christian
McCaffrey Panthers Jersey , both partners go at it
simultaneously.
Favorite dessert
A messy but tasty game, each
partner selects his favorite dessert and recreates that on their partner’s
midsection. So the woman who loves a banana split plops three scoops of ice
cream on the man’s banana, adds sauce, nuts, whipped cream, etc. and – bon
appetit! Afterward Marquis Haynes
Panthers Jersey , the man indulges his desire for chocolate cake by
spreading icing all around his partner’s female organ.
Drinking game
variation
Select a movie or TV show. Set up rules that whenever someone
says or does a certain thing, one of the partners performs oral sensual activity
on the other. For example, if watching a football game, the man goes down
whenever team A has the ball and does so until team B gets the ball, at which
point the woman returns the favor. (If choosing a movie or TV series, try to
pick one that has a certain amount of repetitiveness Rashaan
Gaulden Panthers Jersey , such as a catchphrase that is uttered
often, or a tendency for the main character to wear yellow, etc., and use those
as the guide for knowing when to perform.)
