The study appears in a 27 September issue of the journal Stem Cells Translational Medicine.

iPS cells have properties similar to embryonic stem cells, which are "master cells" with an unlimited capacity to differentiate into any type of tissue in the body, such as brain, lung, skin, heart, and liver. Thus their potential in regenerative medicine, where damaged or diseased tissue can be repaired or replaced by growing new tissue, is huge, as senior author Timothy Nelson explains in a press release:

"Pluripotent stem cells show great promise in the field of regenerative medicine; however, the risk of uncontrolled cell growth will continue to prevent their use as a therapeutic treatment."

Nelson is Assistant Professor of Medicine and Pharmacology and works in the General Internal Medicine department and the Transplant Center at the Mayo.

The idea of using iPS cells is for doctors to be able to take some adult tissue, for example skin cells, from the patient who needs the treatment, and then turn the cells from that tissue into iPS cells.

Then, those iPS cells are coaxed to turn into the target type of cell, for instance lung cells. As a result of the coaxing the iPS cells turn into (differentiate) the target tissue type.

Purging Stem Cells To Make Therapy Safer

(WGBA/NBC) - It is a story that gives hope to pet owners all over the country stem cell therapy for animals suffering from problems like arthritis or hip displaysia.

Stem cells are taken out of the dog's fatty tissue are harvested then injected into problem areas leaving the dogs completely healed.

"We couldn't take him on walks, he just laid around a lot," said Keith Nosowiak, Deniro's owner.

"We'd hear whimpering overnight, she'd take a few steps and she would sit down," said Luther Kortbein, Shadow's owner.

Until two months ago, Deniro suffered from severe arthritis, Shadow from hip displaysia.

Deniro's owner thought he may even have to put his German shepherd down.

"We felt we had a decision to make with his quality of life and being in pain we didn't want him to be in pain," Noskowiak said.

Shadow's owner was willing to try anything to cure her.

"Whatever the cost needed to get this done we were willing to do," Kortbein said.

Then Packerland Veterinary Center offered them stem cell therapy by using the dogs own stem cells and then injecting them back into the bloodstream joints.

Probe sought into status of stem cell therapy in the Philippines

According to Aristotle, only the Pentacosiomedimnoi were eligible for election to high office as archons and therefore only they gained admission into the Areopagus. A modern view affords the same privilege to the hippeis. The top three classes were eligible for a variety of lesser posts and only the Thetes were excluded from all public office.

Depending on how we interpret the historical facts known to us, Solon's constitutional reforms were either a radical anticipation of democratic government, or they merely provided a plutocratic flavour to a stubbornly aristocratic regime, or else the truth lies somewhere between these two extremes.

Solon's reforms can thus be seen to have taken place at a crucial period of economic transition, when a subsistence rural economy increasingly required the support of a nascent commercial sector. The specific economic reforms credited to Solon are these: Fathers were encouraged to find trades for their sons; if they did not, there would be no legal requirement for sons to maintain their fathers in old age. Foreign tradesmen were encouraged to settle in Athens; those who did would be granted citizenship, provided they brought their families with them. Cultivation of olives was encouraged; the export of all other produce was prohibited. Competitiveness of Athenian commerce was promoted through revision of weights and measures, possibly based on successful standards already in use elsewhere, such as Aegina or Euboia or, according to the ancient account but unsupported by modern scholarship, Argos

It is generally assumed, on the authority of ancient commentators that Solon also reformed the Athenian coinage. However, recent numismatic studies now lead to the conclusion that Athens probably had no coinage until around 560 BC, well after Solon's reforms.

Solon's economic reforms succeeded in stimulating foreign trade. Athenian black-figure pottery was exported in increasing quantities and good quality throughout the Aegean between 600 BC and 560 BC, a success story that coincided with a decline in trade in Corinthian pottery. The ban on the export of grain might be understood as a relief measure for the benefit of the poor. However, the encouragement of olive production for export could actually have led to increased hardship for many Athenians since it would have led to a reduction in the amount of land dedicated to grain. Moreover an olive produces no fruit for the first six years. The real motives behind Solon's economic reforms are therefore as questionable as his real motives for constitutional reform. Were the poor being forced to serve the needs of a changing economy, or was the economy being reformed to serve the needs of the poor?

Solon's reform of these injustices was later known and celebrated among Athenians as the Seisachtheia (shaking off of burdens). As with all his reforms, there is considerable scholarly debate about its real significance. Many scholars are content to accept the account given by the ancient sources, interpreting it as a cancellation of debts, while others interpret it as the abolition of a type of feudal relationship, and some prefer to explore new possibilities for interpretation. prohibition on a debtor's person being used as security for a loan. release of all Athenians who had been enslaved.

The removal of the horoi clearly provided immediate economic relief for the most oppressed group in Attica, and it also brought an immediate end to the enslavement of Athenians by their countrymen. Some Athenians had already been sold into slavery abroad and some had fled abroad to escape enslavement Solon proudly records in verse the return of this diaspora. It has been cynically observed, however, that few of these unfortunates were likely to have been recovered. It has been observed also that the seisachtheia not only removed slavery and accumulated debt, it also removed the ordinary farmer's only means of obtaining further credit.

The seisachtheia however was merely one set of reforms within a broader agenda of moral reformation. Other reforms included: the abolition of extravagant dowries. legislation against abuses within the system of inheritance, specifically with relation to the epikleros (i.e. a female who had no brothers to inherit her father's property and who was traditionally required to marry her nearest paternal relative in order to produce an heir to her father's estate). entitlement of any citizen to take legal action on behalf of another. the disenfranchisement of any citizen who might refuse to take up arms in times of civil strife, a measure that was intended to counteract dangerous levels of political apathy.

The personal modesty and frugality of the rich and powerful men of Athens in the city's subsequent golden age have been attested to by Demosthenes. Perhaps Solon, by both personal example and legislated reform, established a precedent for this decorum. A heroic sense of civic duty later united Athenians against the might of the Persians. Perhaps this public spirit was instilled in them by Solon and his reforms. Also see Solon and Athenian sexuality

The literary merit of Solon's verse is generally considered unexceptional. Solon the poet can be said to appear 'self-righteous' and 'pompous' at times and he once composed an elegy with moral advice for a more gifted elegiac poet, Mimnermus. Most of the extant verses show him writing in the role of a political activist determined to assert personal authority and leadership and they have been described by the German classicist Wilamowitz as a "versified harangue" (Eine Volksrede in Versen). According to Plutarch however, Solon originally wrote poetry for amusement, discussing pleasure in a popular rather than philosophical way. Solon's elegiac style is said to have been influenced by the example of Tyrtaeus. He also wrote iambic and trochaic verses which, according to one modern scholar, are more lively and direct than his elegies and possibly paved the way for the iambics of Athenian drama.
