Wikipedia
The cell group is a form of church organization that is used in some Christian churches. Cell groups are generally intended to teach the Bible and personalize Christian fellowship. They are always used in cell churches, but also occur in parachurch organizations and other interdenominational settings, where they are usually referred to as such as Bible study groups. They are known by a variety of other names, including growth groups, connect groups, care groups, life groups, fellowship groups, small groups and home groups. David Hunsicker suggests that the "cell" group concept in church structure "is becoming prominent in almost every denomination in American Protestantism."
The cell group differs from the house church in that the group is part of an overall church congregation, whereas the house church is a self-contained congregation.
